Original question: 1/84-3/200
Solution:
1 84 | － | 3 200 |
Divide the least common multiple 4200 by the denominator 84 of the minuend to get 50
Multiply the numerator 1 and denominator 84 of the subtracted number by 50
Then divide the least common multiple 4200 by the denominator 200 of the subtraction to get 21
Multiply the subtracted numerator 3 and denominator 200 by 21 at the same time
| = | 50 4200 | － | 63 4200 |
| = | - | 13 4200 |
