Question

Alice is making hats. It takes 1/3 a yard of fabric to make 3 hats. How much fabric is needed to make 1 hat?​

Answer 1

1/9

Explanation:

1/3 yard = 3 hats

x yard = 1 hat

*cross multiply*

3x = 1/3

x = 1/3 divided by 3

x = 1/3 (kept) multiplied by (changed) 1/3 (flipped)

therefore x = 1/9
