Question

a test consisted of 15 multiple choice questions 10 true/false questions, and 10 fill in the blank questions maria got 9 questions wrong what percent of her answeres were correct?

Answer 1

15+10+10=35
that's how many you have possible.
9-35=26
that's how many you got right
so divide the possible by the right
26/35=0.7428...
so if you want a % you carry the decimal twice to the right and destroy the rest of the numbers so you got a 74%
