Original question: 9/11-1/8
Solution:
9 11 | － | 1 8 |
Divide the least common multiple 88 by the denominator 11 of the minuend to get 8
Multiply the numerator 9 and denominator 11 of the subtracted number by 8
Then divide the least common multiple 88 by the denominator 8 of the subtraction to get 11
Multiply the subtracted numerator 1 and denominator 8 by 11 at the same time
| = | 72 88 | － | 11 88 |
| = | 61 88 |
