Original question: 198/245-13/11
Solution:
198 245 | － | 13 11 |
Divide the least common multiple 2695 by the denominator 245 of the minuend to get 11
Multiply the numerator 198 and denominator 245 of the subtracted number by 11
Then divide the least common multiple 2695 by the denominator 11 of the subtraction to get 245
Multiply the subtracted numerator 13 and denominator 11 by 245 at the same time
| = | 2178 2695 | － | 3185 2695 |
| = | - | 1007 2695 |
