If someone is two-thirds of there fathers height and they are 54 inches how tall the dad?

To find the dad's height, we can use the given information that the person is two-thirds of their father's height. Let's denote the father's height as \(h\). Then, we can write the equation:

\(0.67h = 54\)

To solve for \(h\), we need to isolate it on one side of the equation. We can do this by dividing both sides by 0.67:

$$\frac{0.67h}{0.67} = \frac{54}{0.67}$$

Simplifying the division, we get:

$$h = \frac{54}{0.67} \approx 80.6$$

Therefore, the dad's height is approximately 80.6 inches.
