Simple....
you have:
to convert them into improper fractions:
1.) Take whole number*denominator
(5*5=25)
2.) Take what you got...and add the numerator
(25+2=27)
3.) Use the original denominator
Do the same to the other one...
2*13=26
26+10=36
Now..add...
But..you need a common denominator!
Now you can add!
When simplified....
Thus, your answer.
