[ 1/1 Fraction calculation ]
Question type: Fractional subtraction
Original question: 13/9-6/13
Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 9 and 13 respectively,their least common multiple is 117
Divide the least common multiple 117 by the denominator 9 of the minuend to get 13
Multiply the numerator 13 and denominator 9 of the subtracted number by 13
Then divide the least common multiple 117 by the denominator 13 of the subtraction to get 9
Multiply the subtracted numerator 6 and denominator 13 by 9 at the same time
