    Divide two fractions with defferent denominators:The denominators of two fractions are 2 and 100 respectively,their least common multiple is 100
    Divide the least common multiple 100 by the denominator 2 of the minuend to get 50
    Multiply the numerator 7 and denominator 2 of the subtracted number by 50
    Then divide the least common multiple 100 by the denominator 100 of the subtraction to get 1
    Multiply the subtracted numerator 23 and denominator 100 by 1 at the same time
    =
