there are 75 students in a speech contest. Yesterday, 1/3 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 :

Answer:

30 students

Step-by-step explanation:

Yesterday: 1/3 of the 75 students (75 / 3) = 25 students

There are now 50 students remaining to give their speeches.

Today: 2/5 of the 50 students (50 / 5 = 10 x 2 ) = 20 students

50 - 20 = 30 students remaining to give their speeches.
