What is x when 99 divided by x equals 6?

To find the answer, just divide the dividend by the quotient: 99 ÷ 6 = 16.5

To prove this, let's compute 99 divided by 16.5: $\frac{99}{16.5} = 6$

How does it work?

Asking what the value of x could be when 99 divided by x gives a result of 6, is equivalent to solving the following equation:

$\frac{99}{x} = 6$

Multiply both sides by x: $\frac{99 x}{x} = 6 x$
$\frac{99 x}{x}$ is equivalent to $\frac{x}{x} \times 99$ , which simplifies to $1 \times 99$ (or just $99$ ).
Thus, the equation becomes: $99 = 6 x$
To find x, divide both sides by 6: $\frac{99}{6} = \frac{6 x}{6}$
Which gives, after simplification: $16.5 = x$ (or $x = 16.5$ )

So, if the dividend is 99 and the quotient is 6, the divisor is 16.5.
