[ 1/1 Fraction calculation ]
Question type: Fractional subtraction
Original question: 4/165-2/495
Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 165 and 495 respectively,their least common multiple is 495
Divide the least common multiple 495 by the denominator 165 of the minuend to get 3
Multiply the numerator 4 and denominator 165 of the subtracted number by 3
Then divide the least common multiple 495 by the denominator 495 of the subtraction to get 1
Multiply the subtracted numerator 2 and denominator 495 by 1 at the same time
Calculation result:
The calculation result is reduced by 5

Original question: 4/165-2/495
Solution:
4 165 | － | 2 495 |
Divide the least common multiple 495 by the denominator 165 of the minuend to get 3
Multiply the numerator 4 and denominator 165 of the subtracted number by 3
Then divide the least common multiple 495 by the denominator 495 of the subtraction to get 1
Multiply the subtracted numerator 2 and denominator 495 by 1 at the same time
| = | 12 495 | － | 2 495 |
| = | 10 495 |
