Supporting grades: 7

Description: Sal evaluates 0.79 - 4/3 - 1/2 + 150%. Created by Sal Khan. So the easiest thing to do would be to write all of these in the same format. And for me, the easiest format to do this computation in would be to write them all as fractions. And the reason why I want to do that, in particular, is because 4/3, when you divide by 3, when you divide 1/3, 2/3, 4/3, you're going to have a repeating decimal.
