Xiaohong is twice as much as Xiaofang, so they are three times as much as Xiaofang, so they can be divided by 3. The remainder is 1. So Xiaoli divided by 3, the remainder is 155 △ 3, the quotient = 18, Xiaoli is the least, so it must not be more than 18, more than 10, and the remainder divided by 3 is 1, so it is 16 or 13. If Xiaoli is 16, then the other two are 55-16 = 39, then Xiaofang is 39 △ 3 = 13
