Match each term with the example that most closely represents it. You can add two fractions using fraction strips, number lines, or by using a common denominator. Determine each sum. Subtraction of Fractions You can subtract two fractions using fraction strips, number lines, or by using a common denominator. Determine each difference. Multiplication of Fractions You can use an area model to help you visualize the product of two fractions. Determine each product.

How else might you calculate the difference in trip times? Construction materials are also sold in imperial units. This leads to calculations involving mixed numbers. Doug used a calculator that can perform fractional operations.

In the imperial number 2 system. You can rename the mixed number with its whole number part reduced by one and its fraction part increased accordingly.

Draw a number line with intervals that correspond to the LCD of the fractions. You can rename the fraction part as a mixed number and add once more. Use number lines to evaluate the following expressions.

Evaluate the expressions in question 6. Use fraction strips to explain how to evaluate each expression. Between which two whole numbers will each sum lie?

Use the diagrams to help you evaluate each expression. What is the value of each expression? Evaluate the expressions in question 4. A recipe for cookies calls for 1 c chopped dates. When these ingredients are combined.

Alexis left her house at 7: She returned at You may use diagrams to show your C explanations. Determine two mixed numbers. Zofia spent 4 h weeding her garden on 3 4 Monday and 1 h on Tuesday. Explain each of the following. How many 5 hours did she spend weeding her garden altogether?

John trains by running on the school track. Extending 1 1 When he gets tired. Jane is putting wood trim around a doorway like the 1" 38 — 8 one shown to the right. His log for one training day is shown to the left. How many linear feet of wood will Jane need altogether?

The sum of two mixed numbers is 2 more than the difference. What 2 are the two numbers? It represents 5 mm or 0. The marking halfway between 0 and 1 cm is a little longer than the other markings.

Before Most people know their height in feet and inches. The distance between adjacent markings represents 1 mm or 0. Use the photo of the measuring tape to estimate the number of centimetres in one inch.

Because of this. What measurement. The distance between adjacent markings represents of an inch. Calculate the total length in inches of A. Once the transfer is complete. How many small boxes of cans were moved to the basement?

How many large boxes would hold all the cans that are now in the basement? The cans in the kitchen of the food shelter will fill Four small boxes were moved to the basement. The area 1 1 small box 1 — 3 — 3 3 2 1— 2 told me how many small boxes Mario would fill 1 1 2 1 with soup cans. I drew a rectangle 2 by 1.

I simplified by dividing. Bobby changed the mixed numbers to improper fractions before he multiplied. I marked off the number of times I could fit the 0 1 2 3 4 5 6 7 8 1 3 3 divisor 1 into the dividend 7. I had to divide to 2 1 3 determine how many 1 s were in 7. I knew that my work was correct. Using an area model 1 5— 3 I thought of a rectangle that had 3 a length of 2 units and a width 4 3 1 2— 4 of 5 units.

I simplified the fractions 4 3 4 3 3 4 2 before I multiplied. How could Carly determine the partial areas without drawing all the squares? I 4 3 1 multiplied the numerators and the denominators.

I think 4 the volume might be close to 25 cm3. I would need 2 boards for every 2 24 33 11 foot of width. For 16 ft. He bought boards that are 3 11 10 ft long.

You can then determine the area of each section of the rectangle. The product of the mixed fractions is the sum of these partial areas. State the division problem and its answer shown by the number line. Calculate each quotient. Calculate each product.

Calculate each power. A 2 a Determine the perimeter of the chicken coop. Determine the value that makes each equation true. Gavin made a patio area out of square blocks that are 1 ft by 1 ft.

A farmer made a square chicken coop with a length of 6 yd. Show that dividing a number by 5 gives the same answer as C 2 2 multiplying the number by. What are two possibilities for the mixed number? The quotient was a whole 4 number larger than Sherri divided a mixed number by 2.

A rectangle measuring 8 units by 3 units is to be completely 4 4 covered by squares that are all the same size. They get the correct answer. Without calculating the quotient. A large bottle holds 1 times the amount of liquid of a small bottle. What are the largest possible dimensions of the squares?

Extending 3 Some people multiply fractions by first renaming them as equivalent fractions with a common denominator. Suppose you won a contest and you had to answer this question: What is the answer to the skill-testing question?

For the first power. I knew that when the base is negative and the exponent is odd. How is the use of the order of operations to evaluate an integer expression similar to evaluating a whole number expression?

How is it different? Tech Support I also had to make sure that I Many graphing calculators use used the negative sign key to a key with a negative sign enter negative numbers instead inside brackets - to of the subtraction key. Using a calculator with brackets keys My calculator only had round brackets so I had to be careful to make sure that the brackets matched the order in the original expression.

Many scientific and graphing calculators are programmed to follow the order of operations. Add and Subtract from left to right. This results in a numerical expression that can be calculated following the order of operations. Calculate Exponents and square roots next. Divide and Multiply from left to right. Perform the operations in Brackets first.

Peng used her graphing calculator to calculate the answer. To evaluate an algebraic expression for given values of the variables. Without calculating. A Redo the solution. Explain what was done incorrectly. Determine the values. Evaluate each expression without using a calculator. Show the steps required to evaluate the following expressions. Without using a calculator. Find the error in each solution. Extending How could you get the power in part b just by looking at the question in part a?

Assume b and n are positive integers. For each situation below. Explain your reasoning. You can also rename the mixed numbers as improper fractions with a common denominator. You may be able to simplify parts of the fractions prior to multiplying.

What strategies can you use to add or subtract mixed Study Aid numbers? Examples 1 and 3.

The most efficient method is to create equivalent fractions with the Examples 1 and 2. What strategies can you use to multiply mixed numbers? Study Aid A1: Rename mixed numbers when necessary. What strategies can you use to divide mixed numbers? You may be able to simplify parts of the fractions prior to Questions 6 and 7. The most efficient method is to rename the mixed numbers as improper Example 2.

Use the model to determine the partial areas and add them to calculate the final product.

You can use a rectangular area model to represent the product of two mixed numbers. What strategies can you use to evaluate integer expressions Study Aid with powers?

Examples 1. When you evaluate an expression for given values for the variable s. Questions 12 and Mid-Chapter Review A2: You can first rename the mixed numbers as equivalent improper fractions with the same denominator. The shelves are to be equally 1 1 3 2 spaced in the cupboard. Calculate each quotient without using a the same value as On Friday 29 —"1 2 1 5" — he worked 3 h and on Saturday he 8 4 1 worked 6 h.

Melissa is adjusting the two removable shelves in 1. Answer the following skill-testing question.

Lesson 1. Explain how you can use estimation to tell that your answers in question 1 are reasonable. Suppose the onscreen 4. John works part-time at a restaurant. Determine at least four other powers that have 6. How many hours did he work 2 altogether? Calculate each product without using a calculator screen. What might the temperature be? I estimated the a number that can be expressed 3 as the quotient of two integers positive value to be about I marked the —20 —10 0 10 20 opposite of the value because I can read fractions more easily if rational number they are positive.

Using fractions and a number line 3 —18 — 18 — 3 I marked the approximate position 4 4 of the temperature value on a number line. I estimated the positive value to be about I marked the opposite of the value because I can read decimals more easily if they are positive. How are rational numbers similar to fractions and integers? How are they different?

Using decimals and a number line — A possible temperature value is I knew that the opposite of When it is necessary to compare the size of two or more rational numbers. As a decimal. The symbol Q is used for rational numbers because they are a quotient of two integers.

Since 1 is farther 10 10 10 3 4 —2 —1 0 1 2 from zero than 1. Rename the following rational numbers as quotients of two integers. Rename the following rational numbers as decimals. Rename the following rational numbers as quotients of integers. When reading from left to right: Tammy or Jasmine? Identify the error made in the incorrect solution. Explain how you know each Communication Tip statement is true. Identify the values represented by a. Who did it correctly. Use 7. Explain why.
