Question

Mr. Carver is mixing soil for his garden. He wants the soil to be in the proportion of 1 part sand to 3 1/2 parts compost.

PART A

Complete the table to show how much compost he needs to add for each amount of sand to maintain the proportional relationship.

Sand: 1 - 3 - 5 - 7

Compost: 3 1/2 - ___ - ___ - ___ -


PART B

What is the unit rate of parts compost to parts sand? What is the unit rate of parts sand to parts compost?

Answer 1

10 1/2 - 17 1/2 - 24 1 /2

Explanation:

You multiply 3 1/2 by each part sand. So, 3 times 3 1/2, 5 times 3 1/2, and 7 times 3 1/2 :). The unit rate is 2/7 parts compost to one part sand, and 1 part sand to 3 1/2.
