Original question: 1/30-1/330
Solution:
1 30 | － | 1 330 |
Divide the least common multiple 330 by the denominator 30 of the minuend to get 11
Multiply the numerator 1 and denominator 30 of the subtracted number by 11
Then divide the least common multiple 330 by the denominator 330 of the subtraction to get 1
Multiply the subtracted numerator 1 and denominator 330 by 1 at the same time
| = | 11 330 | － | 1 330 |
| = | 10 330 |
| = | 1 |
| = | 1 33 |
