To evaluate (find the value of) the expression: %2884%2Fz%29+-+6 for z = 7, you just replace the z in the expression with its eqivalent (7) and do the arithmetic. So, it would look like this:
%2884%2F7%29+-+6+=+12+-+6 = 6

Similarly for 48%2Fh%29%2A2 for h = 8 Replace the h with 8.
%2848%2F8%29%2A2+=+6%2A2 = 12
