Question

If Ruby plans on making 4 batches of pancakes, how many combined cups of powdered milk and whole wheat flour does she need?

Answer 1

Ruby needs a cup of powdered milk and six cups of whole wheat to prepare four batches of pancakes.

Given the quantities of powdered milk and whole wheat to prepare a batch of pancakes, we can determined the total amount of each ingredient by simple rule of three:

Powdered milk

$x = 4\,batches\times \frac{1}{4}\,\frac{cups}{batch}$

$x = 1\,cup$

Whole wheat

$y = 4\,batches \times \frac{3}{2}\,\frac{cup}{batch}$

$y = 6\,cups$

Ruby needs a cup of powdered milk and six cups of whole wheat to prepare four batches of pancakes.
