Answer 1

1/8 of a cup or 2 tablespoons

Answer 2

4/5th of a cup of flour

Explanation:

4 cups flour to 5 batches brownies = x cups flour to 1 batch brownies

4 / 5 = x / 1......cross multiply because this is a proportion

(5)(x) = (4)(1)

5x = 4.....divide both sides by 5

x = 4/5

so he used 4/5 of a cup of flour to make 1 batch of brownies <==
