Answer 2

SCHOOL - A

Step-by-step explanation:

1st step - we have to find the L.C.M of 20, 25 and 15 to make the denominators like. The L.C.M of 20,25and 15 is 300

2nd step - we have to multiply each ratio by 300 like 3/20×300 = 45,

4/25×300 = 48 and

4/15×300 = 80

3rd step - compare them like 45/300 < 48/300 < 80/300

we got that 45 / 300 is the lowest which is 3 / 20

Therefore, we got that School A has the lowest teacher to student ratio
