Question

There are 45 students in a speech contest. Yesterday, 2/3 of them gave their speeches. Today, 4/5 of the remaining students gave their speeches. How many students still haven't given their speeches

Answer 1

45 x 2/3 = 30
45-30 = 15

15 x 4/5 = 12
15-12= 3

3 have not yet given their speeches.

Answer 2

3 students because 2/3 of 45 is 30 then 4/5 of 15 is 12 so 3 students still haven’t gone
