1/8 = 0.125
So (8.875/0.125) = 71
or you could say that 8.875 is the same as 8.0 + 0.875
so 8.0/(1/8) = 8.0/1 x 8/1 = 8 x 8 = 64 (remember invert and multiply?)
(8.0 x 8)/(1 x 1) and 0.875/1/8 = 0.875/1 x 8/1 = (8.9 x 8)/(1 x 1) the ones on the bottom go away because (1 x 1) = 1 and any number divided by 1 is the same number so this way it ends up as...
64 + 7 = 71
