What is x when 54 divided by x equals 27?

To find the answer, just divide the dividend by the quotient: 54 ÷ 27 = 2

To prove this, let's compute 54 divided by 2: $\frac{54}{2} = 27$

How does it work?

Asking what the value of x could be when 54 divided by x gives a result of 27, is equivalent to solving the following equation:

$\frac{54}{x} = 27$

Multiply both sides by x: $\frac{54 x}{x} = 27 x$
$\frac{54 x}{x}$ is equivalent to $\frac{x}{x} \times 54$ , which simplifies to $1 \times 54$ (or just $54$ ).
Thus, the equation becomes: $54 = 27 x$
To find x, divide both sides by 27: $\frac{54}{27} = \frac{27 x}{27}$
Which gives, after simplification: $2 = x$ (or $x = 2$ )

So, if the dividend is 54 and the quotient is 27, the divisor is 2.
