    I checked your first five answers and they are all wrong. For many of them you have not reduced them to lowest terms.

    You must be mistaken because my answer is not 44/5 it is 4= 4 whole and then 4/5. Still if you think they are wrong then how can I fix them which ones do I have to reduce?

    1. 3 2/5 + 6 1/5 = 9 3/5

    This site shows you how to reduce or simplify fractions.

    I started at the other end ...

    #12 wrong
    #11 , 3 9/12 = 3 3/4
    #10 correct
    #9 , 1 4/8 = 1 1/2
    #8 , 4 6/8 = 4 3/4
    #7 , 4 1/12 = 1 1/3
    #6 , 13 2/24 = 13 1/12

    I don't know where you got these questions, but most of them were not in lowest terms to begin with. That is very unconventional.
    e.g. #3
    2 2/13 + 2 3/6
    should have been
    2 1/4 + 2 1/2

    At this point the result can be obtained mentally.

    Ok i was wrong on the first one but the rest? I am pretty sure they are right.

    Please study the site I posted. Then reduce numbers 2 through 5.

    Reiny helped you on the others.

    For number 7 its not 4 1/12 its 1 4/12. can you check number 5,4,3,2,1 as well.

    answers for 12345:
    1. 9 3/5
    2. 4 1/2
    3. 4 3/4
    4. still 7 6/9
    5. still 10 16/18

    1 and 2 and 3 are correct. The other two are wrong.

  • Math PLEASE HELP - ,

    Type them into WolframAlpha . com with a + sign between the whole number and its fraction.

    For example,

    3 2/5 + 6 1/5 becomes (3+2/5) + (6+1/5)
    3 - 1 8/12 becomes (3) - (1+8/12)
