Dividing Lengths and Fractions

The video tutorial explains how to determine the number of smaller pipe sections that can be cut from a longer pipe. It begins by presenting the problem and suggests solving a simpler version to devise a strategy. The tutorial then demonstrates the mathematical approach using division, applying it to the main problem. Finally, it calculates the number of sections and concludes with the final answer.

What is the length of each smaller section that needs to be cut from the 25 ft pipe?

• 3/5 ft

• 1/3 ft

• 1/2 ft

• 2/3 ft

If a 10 ft pipe is divided into sections of 2 ft each, how many sections will there be?

• 4

• 5

• 6

• 3
