There at 60 students in a speech contest. Yesterday, 2/3 of them gave their speeches. Today 1/4 of the remaining students gave their speeches. How many students still haven’t give their speeches?

Respuesta :

Answer:

15

Step-by-step explanation:

Total students = 60

Number of student who gave speech yesterday = 2/3 of 60

[tex]=\frac{2}{3}*60=2*20[/tex] = 40

Remaining students = 60 - 40 = 20

Number of students who gave speech today = 1/4 of 20

[tex]=\frac{1}{4}*20=1*5=5[/tex]

Number of students who still haven't give speech = 20 - 5 = 15
