[ 1/2 Fraction calculation ]
Question type: Fractional subtraction
Original question: 14/7-1/14
Solution:
14 7 | － | 1 14 |
| = | 2 1 | - | 1 14 |
| = | 2 | - | 1 14 |
Divide the least common multiple 14 by the denominator 1 of the minuend to get 14
Multiply the numerator 2 and denominator 1 of the subtracted number by 14
Then divide the least common multiple 14 by the denominator 14 of the subtraction to get 1
Multiply the subtracted numerator 1 and denominator 14 by 1 at the same time
| = | 28 14 | － | 1 14 |
| = | 27 14 |
