Alright, lets get started.

We have given the ratio 9:45

or


(9)/(45) could be written as
(1)/(5)

Means the given ratio is 1:5.

Means every given number should be in this ratio 1:5.

? : 30 means


(x)/(30) =(1)/(5)

Cross multiplying


5x = 30

Hence x = 6

For 7 : ?


(7)/(x) =(1)/(5)

Cross multiplying

x = 35


For 8 : ?


(8)/(x) =(1)/(5)

Cross multiplying

x = 40


Hence the answers are 6 30, 7 35, 8 40. : Answer

Hope it will help :)
