153 1/2 I thinkOr you have to convert it Good luck

353.5

First, put 345 over 1, (345/1) then put the plus sign, then after that put 17/2 because u have to convert it into a mixed number. Then you have to find a common denominator. The common denominator is 2, so whatever you do to the bottom, you have to do to the top. So 345+345 is 690, then u put it over 2. From that u add and u get 707/2. Then, you divide 707 and 2 and u finally get 353.5
