61 88 | － | 15 22 |
Divide the least common multiple 88 by the denominator 88 of the minuend to get 1
Multiply the numerator 61 and denominator 88 of the subtracted number by 1
Then divide the least common multiple 88 by the denominator 22 of the subtraction to get 4
Multiply the subtracted numerator 15 and denominator 22 by 4 at the same time
| = | 61 88 | － | 60 88 |
| = | 1 88 |
