Question

there are 45 students in a speech contest. Yesterday, 2/3 of them have their speeches. Today, 3/5 of the remaining students give their speeches. How many students still haven't given their speeches?

Answer 1

Total no of students: 45

Students who gave speech yesterday:
2/3 of 45
= 30

Students left= 45-30 = 15
Students who gave speech today:
3/5 of 15
= 9

No. of who still haven’t give speech
= 15-9
= 6 students

Answer 2

Answer:6 students remaining

Step-by-step explanation:Multiply 2/3 *45 which equals 30. If 30 students gave their speech on the first day there are 15 students remaining. Then multiply 3/5 * 15 which equals 9. If 9 of the 15 remaining students gave their speech than 15-9= 6 students remaining.
