Answer:
23/18 or 1 and 5/18
Step-by-step explanation:
7/9+1/2 can't be directly added, so you must find the lowest-common-denominator, which is 18 (multiplying the denominators gets you this number.) You then change the factors to have the common denominator of 18, which would be 14/18 and 9/18. From here, you just simply add those two numbers together.
