What is x when 99 divided by x equals 23?

To find the answer, just divide the dividend by the quotient: 99 ÷ 23 = 4.304347826087

To prove this, let's compute 99 divided by 4.304347826087: $\frac{99}{4.304347826087} = 23$

How does it work?

Asking what the value of x could be when 99 divided by x gives a result of 23, is equivalent to solving the following equation:

$\frac{99}{x} = 23$

Multiply both sides by x: $\frac{99 x}{x} = 23 x$
$\frac{99 x}{x}$ is equivalent to $\frac{x}{x} \times 99$ , which simplifies to $1 \times 99$ (or just $99$ ).
Thus, the equation becomes: $99 = 23 x$
To find x, divide both sides by 23: $\frac{99}{23} = \frac{23 x}{23}$
Which gives, after simplification: $4.304347826087 = x$ (or $x = 4.304347826087$ )

So, if the dividend is 99 and the quotient is 23, the divisor is 4.304347826087.
