Step 1:
We shall find the length of each piece the original rope was cut into.
[tex]\begin{gathered} EL=\frac{1}{3}of\text{ O.L} \\ \text{Where E.L = each length = ?} \\ OL=\text{original length = 12 f}eet \end{gathered}[/tex]Step 2:
We shall substitute into the equation above.
[tex]EL=\frac{1}{3}\times12=4\text{ feet}[/tex]Step 3:
We shall find the number of pieces the original length was cut into by dividing the original length with 4.
[tex]\text{Number of pieces =}\frac{12}{4}=3\text{ pieces}[/tex]Presentation of the Answer.
Charlie will have 3 pieces of rope.
