Question

A plumber has 12 - ft piece of pvc pipe. He needs to cut the pipe into sections 2/15 ft long. How many sections will he be able to cut from pipe

Answer 1

The total length of the pipe is

`=12ft`

The length of each section is

`=(2)/(15)ft`

Let the number of sections be represented as

`=x`

Step 1:The number of sections can be calculated using the formula below

`\text{each length of section = }\frac{\text{total length}}{\text{Number of section}}`

By substituting the values, we will have

`\begin{gathered} \text{each length of section = }\frac{\text{total length}}{\text{Number of section}} \\ (2)/(15)=(12)/(x) \end{gathered}`

Step 2: Cross multiply

`\begin{gathered} (2)/(15)=(12)/(x) \\ 2* x=15*12 \\ 2x=180 \end{gathered}`

Step 3: Divide both sides by 2

`\begin{gathered} 2x=180 \\ (2x)/(2)=(180)/(2) \\ x=90\text{ } \end{gathered}`

Therefore,

The number of sections he will be able to cut from the pipe = 90
