    27/35 is the exact answer

    7/10 is an estimate

    Step-by-step explanation:

    4/7+2/10

    Simplify the fraction

    4/7+1/5

    The common denominator is 35

    4/7*5/5 + 1/5 * 7/7

    20/35 + 7/35

    27/35

    To estimate

    4/7 is close to 1/2

    2/10 is close is 1/5

    1/2 + 1/5 =

    5/10 + 2/10 = 7/10
