3 1/2 + 2 1/2 + 5 1/3 + 1 2/3 =? 12 12/12? am i right?

3 1/2 + 2 1/2 + 5 1/3 + 1 2/3 =

convert all the mixed numbers to fractions

7/2 + 5/2 + 16/3 + 5/3


I first add 7/2 + 5/2 = 12/2
and then I add 16/3 + 5/3 =21/3
so now we have 12/2 + 21/3 now we find a common denominator

so now we have to find a common denominator for 12/2 + 21/3


so
2,4,6,8,10,12
3,6,9,12
12 is the closet

so we times 12/2 by 6 and 21/3 by 4

now we got 72/12 + 84/12

now we add = 156/12

now we divide 12/156 = 12 12/12 am I right?

I think i made a mis calculation, i will re correct the text later.

    You could just say
    3+2+5+1=11
    1/2+1/2=1+1/3+2/3=2
    11+2=13

    6 is the closest. Look at your selection for common denominators again.

    12/2 x 3 = 36/6 and 21/3 x 2 = 42/6

    36/6 + 42/6 = 78/6

    6 into 78 goes 13 times.

    13 x 6 = 78

    Your answer should be 13.

    11 24/12 or 11 4/2, or 11 6/3 is also correct....

    It's so much simpler to just add the whole numbers and then add the fractions' sum to the whole number sum and the answer is 3+2+5+1= 11. 1/2+1/2+1plus 1/3+2/3=1 Therefore,11+ 1+1=13 or 12+12/12 which =12+1 which equals 13.

    I'm going to show how my mind decided to solve this:
    3 1/2 + 2 1/2 + 5 1/3 + 1 2/3
    (3 1/2 + 2 1/2) + (5 1/3 + 1 2/3)
    (6) + (7)
    7 + 6 = 13
