There are 96 students in a speech contest.Yesterday 1/4 of the gave their speeches.Today,1/8 of the remaining students gave their speeches. How many students still haven't given their speeches?
Ajl's answer is incorrect
yesterday 1/4 o 96 or 24 gave their speeches, so
the number who have not given their speeches is 72
Today 1/8 of the 72 gave their speeches or 9 gave their speech.
leaving 63 not yet having given their speeches.
or
(1-14)(1 - 18)(96)
= (3/4)(7/8)(96) = 63
My bad I misread the question. You are right @Reiny
thank u
96-96/4 = 72 remaining.
72-72/8 = 63 remaining.
To find the number of students who still haven't given their speeches, we need to subtract the number of students who have already given their speeches from the total number of students.
Let's break it down step by step:
1. Start with the total number of students: 96.
2. Yesterday, 1/4 of the students gave their speeches. That means 1/4 * 96 = 24 students gave their speeches.
3. Now, we need to find out how many students are remaining after yesterday's speeches. So, subtract the number of students who gave speeches yesterday from the total number of students: 96 - 24 = 72 students are remaining.
4. Today, 1/8 of the remaining 72 students gave their speeches. That means 1/8 * 72 = 9 students gave their speeches today.
5. Finally, to determine the number of students who still haven't given their speeches, subtract the number of students who gave speeches today from the remaining students: 72 - 9 = 63 students still haven't given their speeches.
Therefore, there are 63 students who still haven't given their speeches.
