Try this:
%28-2%2F3%29%282%2F3+-+%281%2F2%29%283%2F4+-+1%2F2%29%29 Start with the inner-most parentheses.
%28-2%2F3%29%282%2F3+-+%281%2F2%29%283%2F4+-+2%2F4%29%29%29 Subtract: 3%2F4-2%2F4+=+1%2F4
%28-2%2F3%29%282%2F3+-+%281%2F2%29%281%2F4%29%29 Multiply: %281%2F2%29%281%2F4%29+=+1%2F8
%28-2%2F3%29%282%2F3+-+1%2F8%29 Subtract: 2%2F3+-+1%2F8+=+16%2F24+-+3%2F24 = 13%2F24
%28-2%2F3%29%2813%2F24%29 Finally, perform the indicated multiplication:
-26%2F72 Simplify.
-13%2F36 ...and there you have it!
