First find the common denominator and change the fractions to equivalent fractions.
11 13/15 = 11 52/60
3 7/12 = 3 35/60
Then add.
11 52/60 + 3 35/60 = 14 87/60 = 15 27/60 = 15 9/20
Now you can try the second problem. I'll be glad to check your work.
please help solved the following fraction
11 13/15 + 3 7/12 =
14 3/4 + 7 + 5 7/8 =
Thanks,
Hannah

Hannah,
For the first problem with the first mixed number, you would multiply 11 and 15 and add 13. So it would be 178/15 because you still use the demominator. Then you mulitply 3 and 12 and add 7. So that would be 43/12.
So the question is 178/15 + 43/12=
Can you solve it from there?
The next one would be 59/4 + 47/8=
Find the common demominators and then solve.

14 87/60 = 15 27/60
Divide 87 by 60 to get 1 27/60.
Add that to 14 to get 15 27/60
