Question

If you can make four hats in an hour how many hats can you make in 4 1/2 hours 

Answer 1

18 hats.

Explanation:

Create equivalent ratios of number of hats to number of hours using the given information.

Let x be the number of hats you can make in 4¹/₂ hours.

`\implies 4:1=x:4.5`

`\implies (4)/(1)=(x)/(4.5)`

Cross multiply:

`\implies 4 * 4.5 = x * 1`

`\implies 18 = x`

Therefore, you can make 18 hats in 4¹/₂ hours.
