Sophia has completed 80% of the problems on her math test. She has completed 32 problems. What is the total number of problems on the test?

40

Step-by-step explanation:

80% of the test = 32 questions

100% of the test = x questions

Cross multiply

80*x = 100 * 32 Combine the right

80x = 3200 Divide by 80

x = 3200/80

x = 40

There are 40 questions on the test.
