find a common denominator:
12=3*2^2
160=5*2^5
3584=7*2^9
so, our common denominator is:
3*5*7*2^9=53760
4480/53760-336/53760-15/53760
4129/53760 is your final answer.

12*160*3584=6881280........Denominator
160*3584=573440
12*3584=43008
12*160=1920
573440 1 573440
573440 times 12 = 6881280
43008 1 43008
43008 times 160 = 6881280
1920 1 = 1920
1920 times 3584 = 6881280

mmc(12 and 160) = 1920
1/12 - 1/160 = (160 - 12)/1920 = 448/1920 = 37/480
mmc(480 and 3584) =
37/480 - 1/3584 =
