Reduce the score to 3 / 6, 15 / 20, 8 / 21, 36 / 72, 42 / 35

Reduce the score to 3 / 6, 15 / 20, 8 / 21, 36 / 72, 42 / 35

3 / 6 = 1 / 2
9 out of 15 = 3 out of 5
20 out of 15 = 1 and 1 out of 3
21 out of 8 = 2 and 5 out of 8
72 out of 36 = 2
35 out of 42 = 5 out of 6

What are the rules of 9 / 5, 16 / 21, 25 / 21, 36 / 32

The molecules are three squared, four squared, five squared
Denominator 5 + 21-5 = 21 + 21-5 * 2 = 32
So 49 / 38 should be filled in the back

What is the law of 12 × 42 = 24 × 21, 13 × 62 = 26 × 31?
What is the law of 14 × 82 = 28 × 41, 46 × 96 = 69 × 64?

When the ratio of the ten digit value to the individual digit value of the multiplier is equal to each digit value and the ten digit value of the multiplied
AB * CD = Ba * DC
A. B, C, D are all one digit values
