Question

There were 150 CEW members scheduled to attend the ANNUAL CEWCONFERENCE. If 14% were absent, how many were present at the conference?

Answer 1

Hello!

The number of members: 150.

Absent: 14%.

Present: 86%.

We can solve this exercise in two ways. I'll show you using the rule of three:

`(150\rightarrow100\%)/(x\rightarrow86\%)`

We will multiply it across:

`\begin{gathered} x\cdot100=150\cdot86 \\ 100x=12,900 \\ x=\frac{12,9\cancel{00}}{1\cancel{00}} \\ x=129\text{ were present} \end{gathered}`
