Solve for R l=PRT

$l = P R T$

Rewrite the equation as $P R T = l$ .

$P R T = l$

Divide each term in $P R T = l$ by $P T$ and simplify.

Divide each term in $P R T = l$ by $P T$ .

$\frac{P R T}{P T} = \frac{l}{P T}$

Simplify the left side.

Cancel the common factor of $P$ .

Cancel the common factor.

$\frac{P R T}{P T} = \frac{l}{P T}$

Rewrite the expression.

$\frac{R T}{T} = \frac{l}{P T}$

Cancel the common factor of $T$ .

Cancel the common factor.

$\frac{R T}{T} = \frac{l}{P T}$

Divide $R$ by $1$ .

$R = \frac{l}{P T}$
