Q. Five thirteenths of the citizens believed that the cause of their difficulty was procrastination. If

400

did not agree with this analysis, how many citizens lived in the community?

Set up equation: First, let's set up the equation based on the information given. If $400$ citizens represent five thirteenths of the community, then the total number of citizens can be found by setting up a proportion.
Solve for $x$ : Next, solve for $x$ by dividing both sides of the equation by $(5/13)$ to isolate $x$ on one side. This involves multiplying by the reciprocal of $5/13$ , which is $13/5$ .
