A student earned a grade of 80% on a math test that had 20 problems. How many problems on this test did the student answer correctly? (round to the nearest whole number) *

16

Step-by-step explanation:

Multiply 20 problems by 5 to get 100%. Then, multiply 20 by 4 to get 80%. We can also convert 80% into a decimal which is 0.80. Then you multiply it by 20.

0.80 × 20 = 16. We multiply it by 20 because that's our total and by 0.80 because that's the amount that we got correct. Had it been 100% then that would mean we got every question right. I hope this helps. Please mark me brainliest, I only need one more. Please! I beg you.
