Solve inequality $9 > 0.3r$ for real number $r$ .

STEP 1

Assumptions
1. The inequality to solve is $9 > 0.3r$ .
2. We need to isolate the variable $r$ to find its range of values that satisfy the inequality.

STEP 2

To isolate the variable $r$ , we need to divide both sides of the inequality by $0.3$ .
$\frac{9}{0.3} > \frac{0.3r}{0.3}$

STEP 3

Perform the division on both sides of the inequality.
$30 > r$

STEP 4

Rewrite the inequality in a more conventional way, with the variable on the left side.
$r < 30$
The solution to the inequality $9 > 0.3r$ is $r < 30$ .
