Is this right??

10 + 7 = 17/100 = 41.2 %

100 + 92 = 192/100 = 1.92 %

15 + 13 = 28/100 = 1.25 %

28 + 22 = 50/100 = .5%

    I don't know what the addition problems are. However, I checked your percentage answers.

    This is right.
    192/100 = 1.92 %

    The others are wrong.

    Remember to divide the numerator by the denominator and then multiply by 100.

    These can you write them out for me?

    100 + 92 = 192/100 = 1.92 %

    15 + 13 = 28/100 = 1.25 %

    28 + 22 = 50/100 = .5%

    I went through them and still came out with these answers? So confused now. I udnerstand what you mean, but it comes out the numerator so I thought they were right? Can you explain each?

    28/100 = ??%

    Did you divide the numerator by the denominator?
