What is x when 31 divided by x equals 17?

To find the answer, just divide the dividend by the quotient: 31 ÷ 17 = 1.8235294117647

To prove this, let's compute 31 divided by 1.8235294117647: $\frac{31}{1.8235294117647} = 17$

How does it work?

Asking what the value of x could be when 31 divided by x gives a result of 17, is equivalent to solving the following equation:

$\frac{31}{x} = 17$

Multiply both sides by x: $\frac{31 x}{x} = 17 x$
$\frac{31 x}{x}$ is equivalent to $\frac{x}{x} \times 31$ , which simplifies to $1 \times 31$ (or just $31$ ).
Thus, the equation becomes: $31 = 17 x$
To find x, divide both sides by 17: $\frac{31}{17} = \frac{17 x}{17}$
Which gives, after simplification: $1.8235294117647 = x$ (or $x = 1.8235294117647$ )

So, if the dividend is 31 and the quotient is 17, the divisor is 1.8235294117647.
