Question

Fia needs 3/4 cup of sugar but only has a a 1/3 cup and a 1/8 cup which one should she use and why

Answer 1

Fia needs 3/4 cub of sugar

She has only a 1/3 cup and a 1/8 cup

To find which cup should she use :

Divide 3/4 by 1/3 and divide 3/4 by 1/8

The operation which give integer number is the true choice

So,

`\begin{gathered} (3)/(4)/(1)/(3)=(3)/(4)\cdot(3)/(1)=(9)/(4)=2(1)/(4) \\ \\ (3)/(4)/(1)/(8)=(3)/(4)\cdot(8)/(1)=(24)/(4)=6 \end{gathered}`

So, it should be use a 1/8 cup, so 6 times of a 1/8 cup will give 3/4 cup of sugar.

So, the answer is : a 1/8 cup
