Aseamstress needs to cut 15 inch pieces of ribbon from a roll of ribbon that is 9 feet in length. what is the greatest number of 15 inch pieces the seamstress can cut from 5 of these rolls of ribbon? explain.

36 pieces of ribbon is what you can get from the 5 rolls. Each roll is 9 feet and 1 foot= 12 inches so we multiply 9 times 12 to get the total number of inches available per roll (108 inches) then times that by 5 the total number of rolls. This brought the total to 540 inches available for the project and divide that by 15 inches and end at 36 pieces.

A= b/2 because u simplying both sides of equation
