    I'll be glad to HELP you with these problems after you tell me what you know and what you don't know about their answers.

    In other words, you make an effort, and we can then help you.

    i add first 107+105=212/2=106/2=53

  • 4th grade -

    i don't this is right or wrong

  • 4th grade -

    i don't no this is right or wrong

    You need to add all four numbers first. Then divide the sum by 4 to find the mean.

  • 4th grade -

    424/4=106

    Right! :-)

    this is all what about another one

  • 4th grade -

    This site shows you how to find the median and the mode.

  • 4th grade -

    the median is 105 and 107
    and i don't about mode

  • 4th grade -

    The median is half way between 105 and 107 -- so the median is 106.

    This set of numbers doesn't have a mode. All of the numbers are different.

    How do you think you can solve the last problem?

  • 4th grade -

    10.00-1.50=$8.50 he receive back
    and my son did 2:50+1:50=4:00 then he subtract 10:00-4:00 =$6:00 he receive back

  • 4th grade -

    He played 4 games. So we multiply 1.50 times 4 = $6.00.

    He paid $2.50 to rent shoes.

    $2.50 + $6.00 = $8.50

    $10.00 - 8.50 = ? change

  • 4th grade -

    10.00-8.50=$1.50

  • 4th grade -

    Right. :-)

  • 4th grade -

    thank you very much for helping me and my son

    You're very welcome.
