1. What is (1/6) divided by (-5/8)
%281%2F6%29%2A%288%2F-5%29=+8%2F-30+=+-4%2F15

2. What is %285%2F16%29%2B+%2811%2F24%29
LCD is the hard part here. Take multiples of 24 until you find one that is divisible by 16. That would be LCD= 48.
%285%2F16%29%2B+%2811%2F24%29
%285%2F16%29%2A%283%2F3%29%2B+%2811%2F24%29%2A%282%2F2%29
%2815+%2B+22%29%2F+48
37%2F48

3. What is %283%2F7%29%2B%28-2%2F9%29
LCD = 63
%283%2F7%29%2B+%28-2%2F9%29
%283%2F7%29%2A%289%2F9%29%2B+%28-2%2F9%29%2A%287%2F7%29
%2827-14%29%2F63
13%2F63
