What is x when 54 divided by x equals 99?

To find the answer, just divide the dividend by the quotient: 54 ÷ 99 = 0.54545454545455

To prove this, let's compute 54 divided by 0.54545454545455: $\frac{54}{0.54545454545455} = 99$

How does it work?

Asking what the value of x could be when 54 divided by x gives a result of 99, is equivalent to solving the following equation:

$\frac{54}{x} = 99$

Multiply both sides by x: $\frac{54 x}{x} = 99 x$
$\frac{54 x}{x}$ is equivalent to $\frac{x}{x} \times 54$ , which simplifies to $1 \times 54$ (or just $54$ ).
Thus, the equation becomes: $54 = 99 x$
To find x, divide both sides by 99: $\frac{54}{99} = \frac{99 x}{99}$
Which gives, after simplification: $0.54545454545455 = x$ (or $x = 0.54545454545455$ )

So, if the dividend is 54 and the quotient is 99, the divisor is 0.54545454545455.
