Understanding Ratios
To solve the problem, we need to calculate the compounded ratio of the given ratios and understand the terms used.
Given Ratios:
- Compounded Ratio: 4:9
- Duplicate Ratio of 3:4
- Triplicate Ratio of 2:3
- 9:7
Calculating Each Ratio:
- Compounded Ratio (4:9): This is already in its simplest form.
- Duplicate Ratio (3:4):
- To find the duplicate ratio, square both terms:
- (3^2):(4^2) = 9:16
- Triplicate Ratio (2:3):
- To find the triplicate ratio, cube both terms:
- (2^3):(3^3) = 8:27
- Ratio (9:7): This is also in its simplest form.
Combining the Ratios:
Now, we need to combine all the obtained ratios:
- Compounded Ratio: 4:9
- Duplicate Ratio: 9:16
- Triplicate Ratio: 8:27
- Final Ratio: 9:7
Finding the Compounded Ratio:
To find the overall compounded ratio:
1. Multiply the numerators:
- 4 * 9 * 8 * 9 = 2592
2. Multiply the denominators:
- 9 * 16 * 27 * 7 = 254016
Thus, the overall compounded ratio is:
Final Compounded Ratio:
- 2592:254016
Simplifying the Ratio:
Upon simplifying 2592:254016, we divide both terms by their GCD:
The simplified ratio is found to be 2:21.
Final Answer:
Therefore, the answer is c) 2:21.
