Original question: 6/7-2/3
Solution:
6 7 | － | 2 3 |
Divide the least common multiple 21 by the denominator 7 of the minuend to get 3
Multiply the numerator 6 and denominator 7 of the subtracted number by 3
Then divide the least common multiple 21 by the denominator 3 of the subtraction to get 7
Multiply the subtracted numerator 2 and denominator 3 by 7 at the same time
| = | 18 21 | － | 14 21 |
| = | 4 21 |
