12 is composite number. 12=1x12 and many more but. Try 1,2,3,4,6
0.10x - 0.08x = 250 - 185
0.02x = 65
x = 3250
13-3/2 you need to make a common denominator, so
26/2-3/2 then subtract the numerators, the denominator remains.
23/2 now simplify the fraction
11½ this is because 22/2+1/2=23/2, and 22/2=11, so 11+1/2 or 11½

Hope that helps :)
