Question

You need to stop that l don't know how to do fraction.​

Answer 1

1 1/4 cups.

Explanation:

This is a subtraction problem since Rob put too much sugar, and he only needed 4 1/8 cups. So:

5 3/8 - 4 1/8 = 1 2/8

Since they have the same denominators all you had to do was subtract the numerators and whole numbers; 5 - 4 = 1, and 3/8 - 1/8 = 2/8.

Now you have 1 2/8, which can be simplified.

1 2/8 = 1 1/4
