Question

To make 5 apple pies, you need about 2 pounds of apples. How many pounds of apples do you need to make 20 apple pies?

Answer 1

You would need `8` pounds of apples to make `20` apple pies.

Explanation:

To work it out, use ratios.

If `2` pounds of apples are required to make `5` pies, then `20` pies, which is `4` times as many pies you are making, will also require `4` times as many apples.

Therefore,

`2 xx 4 = 8`

You will require `8` pounds of apples.
