Step-by-step explanation:
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?
To find the number of students who haven't given their speeches, subtract the number of students who have given their speeches from the total number of students. Yesterday, 14 students gave their speeches and today, 25 more students gave their speeches. So, there are 41 students who still haven't given their speeches.
To find the number of students who haven't given their speeches, we need to subtract the number of students who have given their speeches from the total number of students.
Yesterday, 14 students gave their speeches, so there are 80 - 14 = 66 students remaining.
Today, 25 students gave their speeches, so there are 66 - 25 = 41 students who still haven't given their speeches.
