  1. no, she is not correct....because 1/2 of a small wall is not the same as 1/2 of a large wall. Lets say the small wall is 4 ft....so Sandra painted 1/24 = 2 ft...now lets say the lg wall is 8 ft...so Kenneth painted 1/28 = 4 ft. 

    2. 3 3/8 + 4 1/8
        3 + 4 = 7
        3/8 + 1/8 = 4/8
        7 + 4/8 = 7 4/8....so ur answer is 7 4/8

    3. 5/10 + 68/100 = 50/100 + 68/100 = 118/100
        8/10 + 4/100 = 80/100 + 4/100 = 84/100
        3/10 + 16/100 = 30/100 + 16/100 = 46/100
