The sum 7/4 + 1/2 + 5/3 + 1/3 + 1/4 + 1/2 gives the amount of mix.

1. Which property could you use to change the order of the addends?


2. Which property could you use to change the grouping of the addends?

3. Use these properties to rewrite the number sentence 7/4 + 1/2 + 5/3 + 1/3 + 1/4 + 1/2 in a way that makes the addition easier. Explain how your changes simplify the addition.

4. Simply your sum to find the total amount of soup mix. Show your work.

Answer 1

5

Step-by-step explanation: 3. You can make the addition easier by finding a common denominator 12.

7/4 + 1/2 + 5/3 + 1/3 + 1/4 + 1/2 --> 21/12 + 6/12 + 20/12 + 4/12 + 3/12 + 6/12 need to multiply every numerator and denominator by the same number until the denominator is equal to 12. When it is 12 you can add up all the fractions to get 5.

Answer 2

1. Commutative property

2. Associative property
