Original question: 35/47-12/23
Solution:
35 47 | － | 12 23 |
Divide the least common multiple 1081 by the denominator 47 of the minuend to get 23
Multiply the numerator 35 and denominator 47 of the subtracted number by 23
Then divide the least common multiple 1081 by the denominator 23 of the subtraction to get 47
Multiply the subtracted numerator 12 and denominator 23 by 47 at the same time
| = | 805 1081 | － | 564 1081 |
| = | 241 1081 |
