What is x when 31 divided by x equals 23?

To find the answer, just divide the dividend by the quotient: 31 ÷ 23 = 1.3478260869565

To prove this, let's compute 31 divided by 1.3478260869565: $\frac{31}{1.3478260869565} = 23$

How does it work?

Asking what the value of x could be when 31 divided by x gives a result of 23, is equivalent to solving the following equation:

$\frac{31}{x} = 23$

Multiply both sides by x: $\frac{31 x}{x} = 23 x$
$\frac{31 x}{x}$ is equivalent to $\frac{x}{x} \times 31$ , which simplifies to $1 \times 31$ (or just $31$ ).
Thus, the equation becomes: $31 = 23 x$
To find x, divide both sides by 23: $\frac{31}{23} = \frac{23 x}{23}$
Which gives, after simplification: $1.3478260869565 = x$ (or $x = 1.3478260869565$ )

So, if the dividend is 31 and the quotient is 23, the divisor is 1.3478260869565.
