Question

Beatrice makes a jar of dry soup mix. The ingredients are:

. 1 3/4 = 7/4 cups uncooked rice . 1/3 cup beef bouillon
. 1/2 cup dry lentils . 1/4 cup dried onion flakes
. 1 2/3 = 5/3 cups uncooked pasta . 1/2 cup dried peas

Answer the questions to find out how much soup the recipe makes.
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. Simplify your sum to find the total amount of soup mix. Show your work.

Answer 1

4 8/12

Explanation:

7/4 = 1 3/4

2/4 = 1/2

4/12 = 1/3

1/4 = 1/4

20/12 = 1 2/3

2/4 = 1/2

multiply the numerator and the denominator by 4 because 12 is a factor of 4 and 3

do that to all of the fractions (except the one that already has 12 as the denominator)

the add all of them together because they all have the same denominator
