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?
0.8 * 20 = ?
16
6000
16
20x.8= 16
So what’s the answer
16
To determine the number of problems the student answered correctly, we can use the percentage and the total number of problems.
First, convert the percentage to a decimal by dividing it by 100: 80/100 = 0.8.
Next, multiply the decimal by the total number of problems: 0.8 * 20 = 16.
Therefore, the student answered 16 problems correctly.
