to estimate the sum of difference of 1/8 +1/4, the method is as follows: Rule1 a/b +c/d = (axd) + (bxc) /bxd and Rule2: a/b - c/d = (axd) - (bxc) /bxd. let A=1/8 +1/4=(1x4) +(8x1) / /8x4=4+8 /32=12/32=3/8, and then A=1/8-1/4=4-8/32= -6/32= -3/16. So A=1/8 +1/4=3/8 and A=1/8 -1/4=-3/16Hope this helps. Let me know if you need additional help!
