What is x when 23 divided by x equals 39?

To find the answer, just divide the dividend by the quotient: 23 ÷ 39 = 0.58974358974359

To prove this, let's compute 23 divided by 0.58974358974359: $\frac{23}{0.58974358974359} = 39$

How does it work?

Asking what the value of x could be when 23 divided by x gives a result of 39, is equivalent to solving the following equation:

$\frac{23}{x} = 39$

Multiply both sides by x: $\frac{23 x}{x} = 39 x$
$\frac{23 x}{x}$ is equivalent to $\frac{x}{x} \times 23$ , which simplifies to $1 \times 23$ (or just $23$ ).
Thus, the equation becomes: $23 = 39 x$
To find x, divide both sides by 39: $\frac{23}{39} = \frac{39 x}{39}$
Which gives, after simplification: $0.58974358974359 = x$ (or $x = 0.58974358974359$ )

So, if the dividend is 23 and the quotient is 39, the divisor is 0.58974358974359.
