Step-by-step explanation:

The number of total students is 18+12+10=40

So

1) 18:40 but simplified it will be 9:20

2) 10:40 but simplified it will be 1:4

3) 30:40 but simplified it will be 3:4

4) 30:10 but simplified it will be 3

5) 18:22 but simplified it will be 9:11

N.B simplified means dividing them by their common multiple. so the final answer for each is the number after it is simplified
