Answer 1

To make 16 cookies you will need 1 cup of sugar.

Explanation:

Given:

Sugar needed to make 20 cookies = 1 1/4 cups

To Find:

Sugar needed to make 16 cookies = ?

Solution:

For making 20 cookies 1 1/4 cups of sugar is used

So to make 1 cookie we need

=>
`(1(1)/(4))/(20)`

=>
`((5)/(4))/(20)`

=>
`(5)/(4) * (1)/(20)`

=>
`(5)/(80)`

=>
`(1)/(16)` cups of sugar

Now to make 16 cookies we need,

=>
`16 * \text{sugar needed to make one cookie}`

=>
`16 *(1)/(16)`

=>
`(16)/(16)`

=> 1
