Question

Ms. Hernandez gave her students a math test
a
with 42 questions. If Charlie got 36 questions
right, what percent of the questions did he
answer correctly?

Answer 1

Answer:

85-86%

Step-by-step explanation:

Make it an equation

You want to find the percent out of a hundred, so 42 is 100 since it is all of the questions and 36 is the unknown percent X

36/42 = X/100

36             X

42             100

Cross multiply

Do math and solve for X

36 x 100 = 42 x X

3600=42X

X=85.71
