    There are two ways to do it.

    Get Rid Of Fractions:

    r + 2/8 = 3/2

    Divide the numerators by the dividends instead of keeping fractions

    r + 0.25 = 1.5

    Subtract 0.25 from both sides

    r = 1.25 or 1 1/4 or 5/4

    Keep The Fractions:

    r + 2/8 = 3/2

    Subtract 2/8 from 3/2

    To do this you must find least common denominator

    Start by simplifying 2/8

    r + 1/4 = 3/2

    The LCD is 4 so multiply 3/2 by 2 top and bottom

    r + 1/4 = 6/4

    Subtract 1/4 from both sides

    r = 5/4 or 1 1/4 or in decimal 1.25

    Hope this assists you.

    From yours truly to you,
