Question type: Fractional subtraction
Original question: 1/7-1/16
Solution:
1 7 | － | 1 16 |
Divide the least common multiple 112 by the denominator 7 of the minuend to get 16
Multiply the numerator 1 and denominator 7 of the subtracted number by 16
Then divide the least common multiple 112 by the denominator 16 of the subtraction to get 7
Multiply the subtracted numerator 1 and denominator 16 by 7 at the same time
| = | 16 112 | － | 7 112 |
| = | 9 112 |
