    Question writing Fractions in Order

    I have a question that how can it be found that among different which is the bigger or smaller one ?

    e.g 7/2 , 5/9 , 7/2 , 11/7

    If i have to write in ascending or descending order then how will it be done ?

    Look at the denominators is these fractions. You have 2,7,9

    The lowest common multiple of these is? Make this number the new denominator, they will be easy to order then.

    Here is an example.

    2/5 or 3/7 LCM = 35

    so

    2/5 = (7x2)/35 = 14/35

    3/7 = (5x3)/35 = 15/35

    therefore 3/7 > 2/5

    so 441/126 , 70/126 , 441/126 , 198/126

    1)441/126

    2)198/126

    3)70/126
