Question

Mr. Carver is mixing soil for his garden. He want the soil to be in the proportion of 1 part sand to 3 1/2 parts compost. Complete the table to show how much compost needs to add for 5 parts sand to maintain the proportional relationship

Answer 1

3 parts sand to
`10(1)/(2)` parts compost

5 parts sand to
`17(1)/(2)` parts compost

7 parts sand to
`24(1)/(2)` parts compost

Explanation:

Mr. Carver is mixing soil for his garden.

He want the soil to be in the proportion:

1 part sand to
`3(1)/(2)` parts compost

Then

3 parts sand to
`3(1)/(2)* 3=(7)/(2)* 3=(21)/(2)=10(1)/(2)` parts compost

5 parts sand to
`3(1)/(2)* 5=(7)/(2)* 5=(35)/(2)=17(1)/(2)` parts compost

7 parts sand to
`3(1)/(2)* 7=(7)/(2)* 7=(49)/(2)=24(1)/(2)` parts compost
