Question

suppose 77% of students chose to study French their junior year, and that meant that there were 616 such students. How many chose not to take French their junior year?

Answer 1

Notice that if we find the total number of students, we can find the number of those that decided not to take French by subtracting the ones that took French from the total number of students.

We have the next relations:

`\begin{gathered} 616\to77\text{percent} \\ x\to100\text{percent} \end{gathered}`

In other words:

`\begin{gathered} (616)/(77)=(x)/(100) \\ \Rightarrow x=(616\cdot100)/(77) \\ \Rightarrow x=800 \end{gathered}`

Then, there are 800 students in total

The number of students that did not choose to take French their junior year is:

`800-616=184`

184 is the answer.
