Let's make a ratio!

okay this isn't the elmo show but still, let's start with reducing fractions

14/21 = 2/3 with a factor of 7

Only 2/3 of your "party peeps" can attend, so ...

You only need 2/3 of your recipe!

2/3 of 6 = 4 cups of sugar

2/3 of 3 = 2 eggs

2/3 of 9 = 6 cups of flower

2/3 of 2 = (4/3) cups of oil
