Question
If A: B =7:5 and B:C=9:11 then A: B:C=Options7:45:2924:09:4263:45:5546:03:5055:43:03
Solution
The given ratios are A:B = 7:5 and B:C = 9:11.
To find the ratio A:B:C, we need to make the B term in both ratios equal.
To do this, we multiply the first ratio by 9 (the B term in the second ratio) and the second ratio by 5 (the B term in the first ratio).
This gives us A:B = 63:45 and B:C = 45:55.
Therefore, the ratio A:B:C is 63:45:55.
