Solve for : $\small \frac{s}{p}=t$

$\small s=tp$

$\small s=\frac{t}{p}$

$\small s=\frac{p}{t}$

$\small s=t+p$

$\small s=t-p$

Explanation

In order to solve for $\small s$ , we'll need to get all the other variables to one side so. Right now $\small s$ is being divided by $\small p$ , so we need to multiply the $\small p$ to the other side in order to move it.

$\small \frac{s}{p}=t$

$\small s=(t)p$

$\small s=tp$

Since all the variables are different we can't do anything else to simplify the equation.

Our answer is $\small s=tp$
