Question

Mr. Gehring has 3/4 pound bag of flour to use for 6 cakes. How much flower is used for each cake?

Answer 1

To solve this problem, we can set up a proportion.


0.75          X
         x
  6            1

To solve this proportion, you can use cross products.

The resulting equation is 0.75*1=6x

When the left side is simplified, you get 0.75 = 6x.

You are trying to get x alone, so you need to divide both sides by 6.

0.75/6 = 1/8.  

So, Mr. Gehring uses 1/8 flour for each cake.
