2
99
    Divide two fractions with defferent denominators:The denominators of two fractions are 9 and 99 respectively,their least common multiple is 99
    Divide the least common multiple 99 by the denominator 9 of the minuend to get 11
    Multiply the numerator 1 and denominator 9 of the subtracted number by 11
    Then divide the least common multiple 99 by the denominator 99 of the subtraction to get 1
    Multiply the subtracted numerator 2 and denominator 99 by 1 at the same time
    = 
11
99
