What is x when 23 divided by x equals 9?

To find the answer, just divide the dividend by the quotient: 23 ÷ 9 = 2.5555555555556

To prove this, let's compute 23 divided by 2.5555555555556: $\frac{23}{2.5555555555556} = 9$

How does it work?

Asking what the value of x could be when 23 divided by x gives a result of 9, is equivalent to solving the following equation:

$\frac{23}{x} = 9$

Multiply both sides by x: $\frac{23 x}{x} = 9 x$
$\frac{23 x}{x}$ is equivalent to $\frac{x}{x} \times 23$ , which simplifies to $1 \times 23$ (or just $23$ ).
Thus, the equation becomes: $23 = 9 x$
To find x, divide both sides by 9: $\frac{23}{9} = \frac{9 x}{9}$
Which gives, after simplification: $2.5555555555556 = x$ (or $x = 2.5555555555556$ )

So, if the dividend is 23 and the quotient is 9, the divisor is 2.5555555555556.
