Question

In a school, the ratio of the number of large classrooms to small classrooms is 2:3. If the number of small rooms is 30, then find the number of large rooms.

Answer 1

Answer:

20

Step-by-step explanation:

let the number of small classrooms be '3x'

3x = 30

x=30/3

x=10

let the number of large classrooms be '2x'

therefore but substituting x=10,

2 × 10

= 20 large classrooms
