Find a two mixed numbers such that when you estimate their sum by rounding to the nearest whole number you get a different estimate than when you round to the nearest half.

Not sure about rounding to the nearest half???

  • Math 5th grade -

    2 3/8 + 1 7/8

    Nearest whole number = 2 + 2 = 4
    Nearest half = 2 1/2 + 2 = 4 1/2

    Would this be right? 1-3/8 + 1-3/7

    rounded nearest 1/2 number rounded nearest whole
    1-1/2 1-3/8 1
    1-1/2 1-3/7 1
    Add 3 2

    Thank you Ms. Sue. Could you double check mine.
    I will write the answer like you did for 1 3/8 + 1 3/7

    Nearest whole number = 1 + 1 = 2
    Nearest half = 1 1/2 + 1 1/2 = 3

    Correct?
