Last year 120 students were sick at school this year 20% fewer students are sick how many students are sick this year

96 students

Step-by-step explanation:

Since we are comparing last year to this year, the number if sick students last year would be 100% (or original number of sick students)

Percentage number of students sick this year

= 100% - 20%

= 80%

Note that the percentage of sick students this year is not 20% because of the word 'fewer'.

Number of sick students this year= 80/100 × 120= 96

Or you could also think of it this way:

100% 120 students

80% 120/100 × 80= 96 students
