Question type: Fractional subtraction
Original question: 989/19800-47/49500
Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 19800 and 49500 respectively,their least common multiple is 99000
Divide the least common multiple 99000 by the denominator 19800 of the minuend to get 5
Multiply the numerator 989 and denominator 19800 of the subtracted number by 5
Then divide the least common multiple 99000 by the denominator 49500 of the subtraction to get 2
Multiply the subtracted numerator 47 and denominator 49500 by 2 at the same time
Calculation result:
The calculation result is reduced by 99
