Question

In Marsha’s class, 18 out of 40 students got a perfect score on the test. What percent of the students got a perfect score?

Answer 1

Answer:

the answer is 45 percent

Step-by-step explanation:

18 is near 20 which is 50 percent of 40 and 2 is 5 percent of 40 so just subract 2 from 20 and that equals 45 percent of 40. (Sorry if this explanation is bad I'm not very good at explaining)
