5/8

anonymous · Answer

4x2=8
so
7/8 -2= 5/8

anonymous · Answer

So Rickey has $\large \frac{7}{8}$ and he gives away 2 $\large \frac{1}{4}$ bowls. This can be shown with the equation $$\large \frac{7}{8}~-~(2 \times \frac{1}{4})=~?$$ Can you solve that?

-2/8 not - 2 sorry

You meant:

$\large \dfrac{7}{8}~-~(\dfrac{2}{2} \times \dfrac{1}{4})=$

which then becomes

$\large =\dfrac{7}{8}~-~\dfrac{2}{8} $

$\large =\dfrac{5}{8} $

It says "2 1 over 4 cups". Would that not be $\large 2 \times \frac{1}{4}$?

anonymous · Answer

Since he's giving away 2 $\large \frac{1}{4} \normalsize th$ cups, that's the same as giving away 1/2 cup. So $$\large \frac{7}{8}~-~\frac{4}{8}~=~\frac{3}{8}$$

Sorry. You are absolutely correct. I didn't notice the two spelled out. I only looked at the numbers.
