54/2*3

=81
answer is 81 inches

Answer 2

Naomi's father is 81 inches tall.

Explanation:

Naomi is two-thirds as tall as her father.

Let "x" be the Naomi's father height.

Naomi is 54 inches tall.

`(2)/(3).x = 54`

We need to solve for x.

To solve for x, multiply both sides by the reciprocal of
`(2)/(3)`.

The reciprocal of
`(2)/(3)` is
`(3)/(2)`.

`(3)/(2) . (2)/(3) . x = 54.(3)/(2)`

x =
`54.(3)/(2)`

x = 27.3

x = 81

So, Naomi's father is 81 inches tall.
