☆1 fraction calculations
[ 1/1 Fraction calculation ]
Question type: Fractional subtraction
Original question: 4/5-2/15
Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 5 and 15 respectively,their least common multiple is 15
Divide the least common multiple 15 by the denominator 5 of the minuend to get 3
Multiply the numerator 4 and denominator 5 of the subtracted number by 3
Then divide the least common multiple 15 by the denominator 15 of the subtraction to get 1
Multiply the subtracted numerator 2 and denominator 15 by 1 at the same time
Calculation result:
The calculation result is reduced by 5

Original question: 4/5-2/15
Solution:
4 5 | － | 2 15 |
Divide the least common multiple 15 by the denominator 5 of the minuend to get 3
Multiply the numerator 4 and denominator 5 of the subtracted number by 3
Then divide the least common multiple 15 by the denominator 15 of the subtraction to get 1
Multiply the subtracted numerator 2 and denominator 15 by 1 at the same time
| = | 12 15 | － | 2 15 |
| = | 10 15 |
| = | 2 |
| = | 2 3 |
