Answer:

To find out how many cups of sugar Andrew would need to make one whole batch of brownies, we can set up a proportion based on the information given. Andrew used 1/2 cups of sugar to make 3/5 batches.

1/2 cups of sugar is used for 3/5 batches. To find out how much sugar is needed for one whole batch, we can set up the proportion:

1/2 cups of sugar / 3/5 batches = x cups of sugar / 1 batch

Cross multiply to solve for x:

(1/2) * 1 = (3/5) * x

1/2 = 3/5 * x

x = (1/2) / (3/5)

x = (1/2) * (5/3)

x = 5/6

Therefore, Andrew would need 5/6 cups of sugar to make one whole batch of brownies.
