Answer:

Harry was right in:

  • <u>16 problems</u>.

Step-by-step explanation:

To solve the exercise you must take into account that the total number (80 problems) must be taken as 100% of the exercises, with which, you can identify the number of problems that corresponds to 20% using a rule of three, as shown then:

  • 80 problems = 100%
  • X = 20%

Where X is the number of exercises that corresponds to 20%, then you proceed to operate:

  • <u>X = (20%*80)/100% = 16</u>

So 20% of 80 problems, which was the number Harry hit, is 16 problems.
