Question type: Fractional subtraction
Original question: 1/11-1/13
Solution:
1 11 | － | 1 13 |
Divide the least common multiple 143 by the denominator 11 of the minuend to get 13
Multiply the numerator 1 and denominator 11 of the subtracted number by 13
Then divide the least common multiple 143 by the denominator 13 of the subtraction to get 11
Multiply the subtracted numerator 1 and denominator 13 by 11 at the same time
| = | 13 143 | － | 11 143 |
| = | 2 143 |
