Answer:
- The first one is probably the most elegant solution because it requires the fewest number ... We find the current difference (in absolute value) between the given ratio of 9 and 11. 11 - 9 = 2. Now we divide the desired difference (6) by the current difference (2) ... Process: Let both the number be 9x, 11x since their ratio is 9:11.
