Answer:
1 and 2/7 cups of sugar.
Step-by-step explanation:
The ratio of the amount of flour in the original recipe to the amount in your recipe is 1:12/7. (6 / 7/2 = 6 * 2/7 = 12/7)
Therefore, the amount of sugar you need can be found by 3/4 * 12/7 = 36/28 = 9/7 cups of sugar, which equates to 1 and 2/7 cups.
Hope this helped!
