$\frac{5}{2}$

Step 1

To convert degrees to radians, multiply by $\frac{π}{180 °}$ , since a full circle is $360 °$ or $2 π$ radians.

$\frac{5}{2 °} \cdot \frac{π}{180 °}$ radians

Step 2

Cancel the common factor of $5$ .

Step 2.1

Factor $5$ out of $180$ .

$\frac{5}{2} \cdot \frac{π}{5 (36)}$ radians

Step 2.2

Cancel the common factor.

$\frac{5}{2} \cdot \frac{π}{5 \cdot 36}$ radians

Step 2.3

Rewrite the expression.

$\frac{1}{2} \cdot \frac{π}{36}$ radians

Step 3

Multiply $\frac{1}{2}$ by $\frac{π}{36}$ .

$\frac{π}{2 \cdot 36}$ radians

Step 4

Multiply $2$ by $36$ .

$\frac{π}{72}$ radians
