Answer 2

`p=63/8`

Explanation:

Solve:

`7/p=8/9`

Multiply both sides by `p`.

`pxx7/p=8/9xxp`

Cancel `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`
