Answer:
To make 16 cookies you will need 1 cup of sugar.
Step-by-step 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
=>[tex]\frac{1\frac{1}{4}}{20}[/tex]
=>[tex]\frac{\frac{5}{4}}{20}[/tex]
=>[tex]\frac{5}{4} \times \frac{1}{20}[/tex]
=>[tex]\frac{5}{80}[/tex]
=>[tex]\frac{1}{16}[/tex] cups of sugar
Now to make 16 cookies we need,
=>[tex]16 \times \text{sugar needed to make one cookie}[/tex]
=>[tex]16 \times\frac{1}{16}[/tex]
=>[tex] \frac{16}{16}[/tex]
=> 1
