Question

In a group of 72 students, 7/12 of them participated in recycling activities before. How many students did not participate in recycling activities before?

Answer 1

Answer:

TOTAL NUMBER OF STUDENTS=72

NUMBER OF STUDENTS WHO PARTICIPATED=7/12 × 72

NUMBER OF STUDENTS WHO DID NOT PARTICIPATE=x

NOW (7/12×72)+x = 72

SO. 42+x = 72

x= 72-42 = 30

THEREFORE X = 30 WHICH IS NUMBER OF PARTICIPANTS WHO DID NOT PARTICIPATE IN RECYCLING ACTIVITIES
