What is x when 54 divided by x equals 54?

To find the answer, just divide the dividend by the quotient: 54 ÷ 54 = 1

To prove this, let's compute 54 divided by 1: $\frac{54}{1} = 54$

How does it work?

Asking what the value of x could be when 54 divided by x gives a result of 54, is equivalent to solving the following equation:

$\frac{54}{x} = 54$

Multiply both sides by x: $\frac{54 x}{x} = 54 x$
$\frac{54 x}{x}$ is equivalent to $\frac{x}{x} \times 54$ , which simplifies to $1 \times 54$ (or just $54$ ).
Thus, the equation becomes: $54 = 54 x$
To find x, divide both sides by 54: $\frac{54}{54} = \frac{54 x}{54}$
Which gives, after simplification: $1 = x$ (or $x = 1$ )

So, if the dividend is 54 and the quotient is 54, the divisor is 1.
