Answer 1

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

Answer 2

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?

Answer 3

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

This site shows you how to reduce or simplify fractions.

Answer 4

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.

Answer 5

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

Answer 6

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

Reiny helped you on the others.

Answer 7

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

Answer 8

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

Answer 9

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

Answer 10

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)
