Example: If Betsy gets 3 problems correct out of 4, what percent did she correct?
3 = P (P represents the percent correct)
4=100
Cross multiplication will set up an equation to solve for the answer:
3 x 100 = 4 x P
300 = 4P
300÷4 = 4P÷4
(divide each side by 4)
75 = P
Therefore, Betsy got 75 % correct.
