1, Xiaoming and Xiaohong are stamp collectors. Their stamp ratio is 7: 5. It is understood that Xiaoming has 24 more stamps than Xiaohong. How many stamps do they each have?

Set Xiaoming stamps as 7X and coolies as 5X.

7X-5X=2X=24

X= 12 Xiaoming stamp 84 and Xiaohong stamp 60.

The sum of numerator and denominator of a fraction is 92. If 16 subtracts both numerator and denominator, the ratio of numerator and denominator is 1: 3. Find the original score.

Let the molecule be X.

X- 16/92-X- 16 = 1/3

X=3 1 The score is 31/61.
