    The difference between 4 5/7 and 1 3/4 is 83/28 or 2 27/28

    Step-by-step explanation:

    First, to make it easier to subtract, let's change these numbers to improper fractions.

    4 5/7 = 33/7

    1 3/4 = 7/4

    Now, we have to find the LCM (least common multiple) between 4 and 7.

    4 - 4, 8, 12, 16, 20, 24, 28, 32

    7 - 7, 14, 21, 28, 35, 42, 49

    As you can see, the LCM is 28. So, lets change these fractions to have a denominator of 28.

    33*4 / 7*4 = 132 / 28

    7*7 / 4*7 = 49 / 28

    >>132 - 49 = 83

    So, the difference between 4 5/7 and 1 3/4 is 83/28 or 2 27/28
