    Divide two fractions with defferent denominators:The denominators of two fractions are 2 and 8 respectively,their least common multiple is 8
    Divide the least common multiple 8 by the denominator 2 of the first addend to get 4
    Multiply the numerator 1 and denominator 2 of the first fraction by 4
    Then divide the least common multiple 8 by the denominator 8 of the second addend to get 1
    Multiply the numerator 7 and denominator 8 of the second fraction by 1
