68 right out of 79 is 86 percent. Sounds like a "B."

You use division. For example 13/47 is approximately 0.276 or 28%. 100-28 is 72 so the grade would be a 72.

First, you convert them to 100. 4/20=16/100 The subtract 16 out of 100. 100-16=84

You got 75% correct.Reason:5 is 1/4 of 20, therefore meaning that you got 3/4 correct. And of course 3/4 = .75, or 75%
