[ 1/1 Fraction calculation ]
    Question type: Fractional subtraction
    Original question: 91/1000-19/99000

    Solution:
     
91
1000
 -  
19
99000
    Divide two fractions with defferent denominators:The denominators of two fractions are 1000 and 99000 respectively,their least common multiple is 99000
    Divide the least common multiple 99000 by the denominator 1000 of the minuend to get 99
    Multiply the numerator 91 and denominator 1000 of the subtracted number by 99
    Then divide the least common multiple 99000 by the denominator 99000 of the subtraction to get 1
    Multiply the subtracted numerator 19 and denominator 99000 by 1 at the same time
    = 
9009
99000
 -  
19
99000
Calculation result:
    =
8990
99000
    The calculation result is reduced by 10
    =
899
 8990 
 99000 
9900

    =
