Solve for P I=Prt ; solve for P

$I = P r t$ ; solve for $P$

Rewrite the equation as $P r t = I$ .

$P r t = I$

Divide each term in $P r t = I$ by $r t$ and simplify.

Divide each term in $P r t = I$ by $r t$ .

$\frac{P r t}{r t} = \frac{I}{r t}$

Simplify the left side.

Cancel the common factor of $r$ .

Cancel the common factor.

$\frac{P r t}{r t} = \frac{I}{r t}$

Rewrite the expression.

$\frac{P t}{t} = \frac{I}{r t}$

Cancel the common factor of $t$ .

Cancel the common factor.

$\frac{P t}{t} = \frac{I}{r t}$

Divide $P$ by $1$ .

$P = \frac{I}{r t}$
