Final answer:
Lorraine's buttermilk pie recipe uses 1/2 cup more sugar than Gayla's, with Lorraine using 1 1/4 cups and Gayla using 3/4 cup.
Step-by-step explanation:
To determine how much more sugar Lorraine's buttermilk pie recipe uses than Gayla's, we need to compare the amounts of sugar in both recipes. Lorraine's recipe calls for 1 1/4 cups of sugar, and Gayla's recipe calls for 3/4 cup of sugar. To compare, we subtract the smaller amount (Gayla's) from the larger amount (Lorraine's):
- Convert the fractions to have a common denominator. In this case, the common denominator is 4, so we rewrite the amounts of sugar as fractions over 4:
Lorraine's sugar: 1 1/4 = 5/4
Gayla's sugar: 3/4 = 3/4 - Subtract the two fractions:
5/4 - 3/4 = (5 - 3)/4 = 2/4 - Simplify the resulting fraction:
2/4 = 1/2
Therefore, Lorraine's recipe uses 1/2 cup more sugar than Gayla's.
