Question type: Fractional subtraction
Original question: 91/1000-1/550
Solution:
91 1000 | － | 1 550 |
Divide the least common multiple 11000 by the denominator 1000 of the minuend to get 11
Multiply the numerator 91 and denominator 1000 of the subtracted number by 11
Then divide the least common multiple 11000 by the denominator 550 of the subtraction to get 20
Multiply the subtracted numerator 1 and denominator 550 by 20 at the same time
| = | 1001 11000 | － | 20 11000 |
| = | 981 11000 |
