Answer:
1 5/36
Step-by-step explanation:
need a common denominator which would be 36
to get from 9 to 36 you multiply by 4 so 5 would be multiplied by 4 to get the fraction 20/36
do the same with 7/12 12x3 is 36 and 7x3 is 21 so 21/36
then add 20+21=41
put over 36 41/36
Find if you can lower it which you can:
41 is bigger than 36 by 5 so your ending fraction would be 1 and 5/36 because 5 and 36 don't have a common factor.
