5
11
 -  
5
13
    Divide two fractions with defferent denominators:The denominators of two fractions are 11 and 13 respectively,their least common multiple is 143
    Divide the least common multiple 143 by the denominator 11 of the minuend to get 13
    Multiply the numerator 5 and denominator 11 of the subtracted number by 13
    Then divide the least common multiple 143 by the denominator 13 of the subtraction to get 11
    Multiply the subtracted numerator 5 and denominator 13 by 11 at the same time
    =
