Question

A recipe for bread uses 600 grams of flour. 480 grams must be whole wheat flour, and the rest is white

flour. If you want to make a batch of bread using 120 grams of whole wheat flour, how much white flour do
you need?

Answer 1

We would need 30 grams of white flour.

Explanation:

To find this, we would need to set up a proportion. However, before that, we need to figure out how much white flour the original recipe was calling for. To find that, we would do 600 subtracted by 480, which is 120. This is how we would set up the proportion :

120/480 = x/120

480x = 120(120)

480x = 14400

x = 30

So, we would need 30 grams of white flour! :)
