times both sides by 9
divide both sides by 8

$p = \frac{63}{8}$ $p=63/8$

Solve:

$\frac{7}{p} = \frac{8}{9}$ $7/p=8/9$

Multiply both sides by $p$ $p$ .

$p \times \frac{7}{p} = \frac{8}{9} \times p$ $pxx7/p=8/9xxp$

Cancel $p$ $p$ on the left-hand side.

$color(red)cancel(color(black)(p))^1xx7/color(red)cancel(color(black)(p))^1=8/9xxp$

Simplify.

$7=(8p)/9$

Multiply both sides by $9$ .

$9xx7=(8p)/9xx9$

Cancel $9$ on the right-hand side.

$9xx7=(8p)/color(red)cancel(color(black)(9))^1xxcolor(red)cancel(color(black)(9))^1$

Simplify.

$63=8p$

Divide both sides by $8$ .

$63/8=(color(red)cancel(color(black)(8))^1p)/color(red)cancel(color(black)(8))^1$

Simplify.

$63/8=p$

Switch sides.

$p=63/8$
