3
1000
    Divide two fractions with defferent denominators:The denominators of two fractions are 30 and 1000 respectively,their least common multiple is 3000
    Divide the least common multiple 3000 by the denominator 30 of the minuend to get 100
    Multiply the numerator 1 and denominator 30 of the subtracted number by 100
    Then divide the least common multiple 3000 by the denominator 1000 of the subtraction to get 3
    Multiply the subtracted numerator 3 and denominator 1000 by 3 at the same time
    =
