Question 17865
To solve this you need to determine how many questions the student got right. Subtract 3 from 40. This gives you 37. Then divide 37 by 40. The answer will be a decimal. Move the decimal 2 places to the right, and this gives you a percent. You could also multiply the decimal by 100 to get the percent.
40-3=37
37/40=.925
92.5%
