Answer:
[tex]Size= \frac{1}{2}\ cup[/tex]
Step-by-step explanation:
Given
[tex]Size = \frac{1}{4}\ cup[/tex]
[tex]Scoop = 2[/tex]
Required
Determine the size of cup for 1 scoop
For two scoops, we have:
[tex]Recipe = \frac{1}{4}+ \frac{1}{4}[/tex]
Take LCM
[tex]Recipe = \frac{1+1}{4}[/tex]
[tex]Recipe = \frac{2}{4}[/tex]
[tex]Recipe = \frac{1}{2}[/tex]
This implies that, the amount of recipe is 1/2
If he uses a cup of size 1/2, he would only need 1 scoop.
Hence:
[tex]Size= \frac{1}{2}\ cup[/tex]
