Question

Make a math drawing, starting with a unit square, to help solve the problem

Answer 1

3/4 butter = 1 batch of cookies.

Levi ate 1/6 of the cookies, so he ate 1/6*3/4 of the butter used to make a whole batch.

1/6 * 3/4 = (1*3) / (6*4) = 3/24. Both 3 and 24 are evenly divisible by 3.

So 3/24 = 1/8 cup of butter is in 1/6 of a batch of cookies.

Answer 2

(1/6)(3/4) = your answer
