Answer: 1 11/36
Explanation:
The denominators need to be common so the new denominator would be 36 (36 is the lcd)
Since you multiplied the 4 by 9, your new fraction would be 27/36
Since you multiplied the 9 by 4 your new fraction would be 20/36
You add them together and you get 47/36
Simplify it.
Your new answer is 1 11/36
