If A : B = 3 and B : C = 1 : 2 then A : B : C is?
If A : B = 3 and B : C = 1 : 2 then A : B : C is?
Explanation
Given: A : B = 3 : 1 and B : C = 1 : 2.
To find A : B : C, make the ratio of B the same in both expressions.
A : B = 3 : 1 means A = 3B.
B : C = 1 : 2 means C = 2B.
So, A : B : C = 3B : B : 2B, which simplifies to 3 : 1 : 2.
Now, multiply the entire ratio by 5 to make the B value in all ratios equal: 3 : 5 : 10.
