What is x when 39 divided by x equals 17?

To find the answer, just divide the dividend by the quotient: 39 ÷ 17 = 2.2941176470588

To prove this, let's compute 39 divided by 2.2941176470588: $\frac{39}{2.2941176470588} = 17$

How does it work?

Asking what the value of x could be when 39 divided by x gives a result of 17, is equivalent to solving the following equation:

$\frac{39}{x} = 17$

Multiply both sides by x: $\frac{39 x}{x} = 17 x$
$\frac{39 x}{x}$ is equivalent to $\frac{x}{x} \times 39$ , which simplifies to $1 \times 39$ (or just $39$ ).
Thus, the equation becomes: $39 = 17 x$
To find x, divide both sides by 17: $\frac{39}{17} = \frac{17 x}{17}$
Which gives, after simplification: $2.2941176470588 = x$ (or $x = 2.2941176470588$ )

So, if the dividend is 39 and the quotient is 17, the divisor is 2.2941176470588.
