Question

There are 75 students in a speech contest. Yesterday, 2/5 of them gave their speeches. Today, 1/3

of the remaining students gave their speeches. How many students still haven't given their speeches?

Answer 1

Answer: 30

Work Shown:

2/5 of 75 = (2/5)*75 = 0.4*75 = 30

Yesterday 30 people gave speeches. There are 75-30 = 45 people left.

1/3 of 45 = (1/3)*45 = 15

Then another 15 people gave speeches today. So there are 45-15 = 30 people who haven't given their speeches yet.
