Question type: Fractional subtraction
Original question: 1/56-1/350
Solution:
1 56 | － | 1 350 |
Divide the least common multiple 1400 by the denominator 56 of the minuend to get 25
Multiply the numerator 1 and denominator 56 of the subtracted number by 25
Then divide the least common multiple 1400 by the denominator 350 of the subtraction to get 4
Multiply the subtracted numerator 1 and denominator 350 by 4 at the same time
| = | 25 1400 | － | 4 1400 |
| = | 21 1400 |
| = | 3 |
| = | 3 200 |
