If it is 0.9 meters long and then he cuts the pipe into 4 equal pieces, then you would just do the equaton: 0.9÷4 and the answer would be 0.225
15 pounds of peanuts cost 45 dollars
how much does 1 pound of peanuts cost
ok
15 times (cost per pound)=45
represent cost per pound with 'w'
15 times w=45
15w=45
divide both sides by 15
w=45/15
w=3
cost is $3 per pound
