24 is that right?

- anonymous

So the first week she posted 45 (2/3) or 30 of them and had 15 left.
This week she posted 15 (4/5) of them so had 12 left.

- anonymous

So, 1/3 of the posters were not originally posted. Then, 1/5 of the remaining 1/3 were not posted. So, 1/5 of 1/3 is 1/15. 45/15 = 3.

There are 75 students in a speech contest. Yesterday, 1/5 of them gave their speeches. Today, 1/3 of the remaining students gave their speeches. How many students still haven't given their speeches?

- anonymous

Again 75 total and 1/5 gave their speech -> 75 * 1/5 = 15
60 were left (75 - 15)
60 and 1/3 gave their speech -> 60 * 1/3 = 20
40 left (60 - 20)

- anonymous

1/5 of them were omitted the first time. 1/3 of the 1/5 then gave speeches. 1/5 of 1/3 is 1/15, again. 75/15 = 5.

- anonymous

** who have given their speech...then 75 - 5 = 7- students.
