There are



80
students in a speech contest. Yesterday,



1/4
of them gave their speeches. Today,




2/5
of the remaining students gave their speeches. How many students still haven't given their speeches?

Respuesta :

1/4 of 80 is 20 so there's 60 left the second day.
2/5 of 60 is 24.
60-24=36
There are 36 students left after the second day.

80 ÷4=20 because 1/4 of them gave speeches.

80-20=60 

60÷5=12

12×2=24

60-24=36
