Solve for a (ma)/(th)=1

$\frac{m a}{t h} = 1$

Multiply both sides by $t h$ .

$\frac{m a}{t h} (t h) = 1 (t h)$

Simplify.

Simplify the left side.

Cancel the common factor of $t h$ .

Cancel the common factor.

$\frac{m a}{t h} (t h) = 1 (t h)$

Rewrite the expression.

$m a = 1 (t h)$

Simplify the right side.

Multiply $t h$ by $1$ .

$m a = t h$

Divide each term in $m a = t h$ by $m$ and simplify.

Divide each term in $m a = t h$ by $m$ .

$\frac{m a}{m} = \frac{t h}{m}$

Simplify the left side.

Cancel the common factor of $m$ .

Cancel the common factor.

$\frac{m a}{m} = \frac{t h}{m}$

Divide $a$ by $1$ .

$a = \frac{t h}{m}$
