If 3a = 4b = 5c then what is the ratio A:B:C?

20:15:12

Step-by-step explanation:

First, find the LCM of the numbers 3 4 5 which is 60

Then divide 60 by 3 4 and 5

We get 20 15 and 12 in order so that's the ratio

20:15:12

20 : 15 : 12

Step-by-step explanation:

3a = 4b = 5c

=>  3a = 4b

=>  a = 4/3b

=> 5c = 4b

=> c = 4/5b

Therefore, they are in the ratio :-

a : b : c = 4/3b : b : 4/5b

Multiply throughout by 15 and b cancels throughout.

=> 20 : 15 : 12
