four pieces of pipe measure 2'1 1/4",4'2 3/4",5'1-9/16, and 6'3-5/8 they were all cut from a 20' lengthof pipe. allowing 1/6" waste for each cut, how much pipe do we have left for the rest of the job?

Question

Fraction word problem

Answer 1

4 pieces of pipe need 4 cuts to separate them from a length of pipe so that means 4/6=2/3" is wasted.

20' less ⅔"=19'11⅓". Total length of pipes required=2'1¼"+4'2¾"+5'1⁹⁄₁₆"+6'3⅝"=17'+7"+(4+12+9+10)/16".

The fraction comes to 35/16=2³⁄₁₆". So total length cut is 17'9³⁄₁₆".

What’s left is 19' 11⅓"-17'9³⁄₁₆"=2'2+(16-9)/48"=2'2+7/48=2'2⁷⁄₄₈".
