A's age is 9.09% less than B's age. How to find A:B from this above condition? Answer is 10/11 I tried: 9.09% = 1/11 BA=1/11, so, B=1/11+A, => A/B = A/(1/11+A), or A/B=(B1/11)/B, or A/B = (B1/11)/(1/11+A).

If B's age is 100%, A's age is 9.09% less than B, so A's age is 90.91% 90.91:100 is close to 10:11
