Step 2.1

Factor $12$ out of $180$ .

$\frac{13 p}{12} \cdot \frac{12 (15)}{π}$

Step 2.2

Cancel the common factor.

$\frac{13 p}{12} \cdot \frac{12 \cdot 15}{π}$

Step 2.3

Rewrite the expression.

$13 p \cdot \frac{15}{π}$

Step 3

Combine $13$ and $\frac{15}{π}$ .

$p \cdot \frac{13 \cdot 15}{π}$

Step 4

Multiply $13$ by $15$ .

$p \cdot \frac{195}{π}$

Step 5

Combine $p$ and $\frac{195}{π}$ .

$\frac{p \cdot 195}{π}$

Step 6

Move $195$ to the left of $p$ .

$\frac{195 p}{π}$

Step 7

$π$ is approximately equal to $3.14159265$ .

$\frac{195 p}{3.14159265}$

Step 8

Convert to a decimal.
