Question

b) In a school, there are a total of 6300 classrooms. The ratio of the number of large
classrooms to small classrooms is 1 : 5. Find the number of large classrooms and
small classrooms in the school.​

Answer 1

Step-by-step explanation:

let the common ratio br x

total room = 5x+1x =6x

6300=6x

x=6300/6

x=1050

number of large classrooms = x =1050

number of small classroom=5x=5250

Answer 2

Answer:

1050 large classroms

5250 small classrooms

Step-by-step explanation:

GIVEN :-

Total class rooms = 6300

let x is the number of multiply classrooms

Ratio = 1:5

1x  +   5x  =  6300

x is common

x (1 + 5) = 6300

x (6) = 6300

x = 6300 ÷ 6

x = 1050

Now we can find the NUMBER

Ratio 1x = large classrooms

= 1 × 1050

= 1050 large classroms

Ratio 5x = small classrooms

= 5 × 1050

= 5250 small classrooms
