1 3/8 = 1 + 3 / 8 = 8 / 8 + 3 / 8 = 11 / 8

( 1 3/8 ) / ( 5 / 8 ) =

( 11 / 8 ) / ( 5 / 8 ) =

( 8 * 11 ) / ( 8 * 5 ) =

11 / 5 =

10 / 5 + 1 / 5 =

2 + 1 / 5 =

2 1/5 =

2.2

To find out how much more butter is needed than peanut butter, we need to subtract the amount of peanut butter from the amount of butter.

Given:
Amount of butter = 1 3/8 cup
Amount of peanut butter = 5/8 cup

To subtract fractions, we need to have the same denominator.

Let's convert the mixed fraction (1 3/8) to an improper fraction.

1 3/8 = (8 * 1 + 3) / 8 = 11/8

Now that we have the same denominator (8), we can subtract the fractions:

11/8 - 5/8 = (11 - 5) / 8 = 6/8

Simplifying 6/8, we get:

6/8 = (2 * 3) / (2 * 4) = 3/4

Therefore, there is 3/4 cup more butter needed than peanut butter.
