How many 14-1/4" long pieces can be cut from a 86' long piece of angle iron? Allow 1/8 waste for each cut
kkurt [141]
The number of pieces that we could have in 86' if were going to cut it by 14 1/4 long with 1/8 waste for each cut is 5.98 pieces. This is computed by converting first the fractions into decimal, 14.25 and 0.125, then add it together since there is a waste in every cut, 14.375. Then we will divide 86 inches by 14.375 inches.
