Question

There are 80 students in a speech contest. Yesterday, 1/4

of them gave their speeches. Today, 1/5 of the remaining students gave their speeches. How many

Answer 1

48 students

Explanation:

Answer 2

48 students have not given their speeches

Explanation:

Yesterday 1/4 of them gave their speeches.

1/4 times 80 is 20

Only 20 have their speeches, remaining 80-20, equals 60 students.

The next day, 1/5 of the remaining.

1/5 times 60 equals 12.

All those who had given is 20+12=32.

Yet to give: 80-32=48
