Convert a percent to a decimal (20%=0.2)
Then multiply your total by the decimal.
80 x .2=16
Answer:
Harry was right in:
- 16 problems.
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:
- X = (20%*80)/100% = 16
So 20% of 80 problems, which was the number Harry hit, is 16 problems.
