Question
Ria saw that the school has 9 buildings, each having 10 classrooms. Find the total number of classrooms the school has.
- 97
- 96
- 90
- 94
Hint:
We are given the number of buildings of school of Ria. Each of the building of school has 10 classrooms. We have to find total number of classrooms the school have. We will do it by multiplying the number of buildings by number of classrooms.
The correct answer is: 90
The number of buildings of school are 9.
The number of classrooms per building are 10.
We have to find total number of classrooms. To find the total number of classrooms, we will multiply the number of buildings by number of classrooms per building.
Total number = Number of buildings × Number of classrooms per building
Total number = 9 × 10
= 90
The school of Ria has 90 classrooms.
The right option is 90.
For such questions, we use multiplication.
