Question
Select the correct answerIf A: B =7:5 and B:C=9:11 then A: B:C=Options7:45:2924:09:4246:03:5063:45:5555:43:03
Solution
The correct answer is 63:45:55.
Here's the step-by-step solution:
- Given that 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 the same.
- We can do this by multiplying 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 combined ratio A:B:C = 63:45:55.
