☆1 fraction calculations
[ 1/1 Fraction calculation ]
Question type: Fractional subtraction
Original question: 10/13-16/25
Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 13 and 25 respectively,their least common multiple is 325
Divide the least common multiple 325 by the denominator 13 of the minuend to get 25
Multiply the numerator 10 and denominator 13 of the subtracted number by 25
Then divide the least common multiple 325 by the denominator 25 of the subtraction to get 13
Multiply the subtracted numerator 16 and denominator 25 by 13 at the same time

Original question: 10/13-16/25
Solution:
10 13 | － | 16 25 |
Divide the least common multiple 325 by the denominator 13 of the minuend to get 25
Multiply the numerator 10 and denominator 13 of the subtracted number by 25
Then divide the least common multiple 325 by the denominator 25 of the subtraction to get 13
Multiply the subtracted numerator 16 and denominator 25 by 13 at the same time
| = | 250 325 | － | 208 325 |
| = | 42 325 |
