What is x when 42 divided by x equals 17?

To find the answer, just divide the dividend by the quotient: 42 ÷ 17 = 2.4705882352941

To prove this, let's compute 42 divided by 2.4705882352941: $\frac{42}{2.4705882352941} = 17$

How does it work?

Asking what the value of x could be when 42 divided by x gives a result of 17, is equivalent to solving the following equation:

$\frac{42}{x} = 17$

Multiply both sides by x: $\frac{42 x}{x} = 17 x$
$\frac{42 x}{x}$ is equivalent to $\frac{x}{x} \times 42$ , which simplifies to $1 \times 42$ (or just $42$ ).
Thus, the equation becomes: $42 = 17 x$
To find x, divide both sides by 17: $\frac{42}{17} = \frac{17 x}{17}$
Which gives, after simplification: $2.4705882352941 = x$ (or $x = 2.4705882352941$ )

So, if the dividend is 42 and the quotient is 17, the divisor is 2.4705882352941.
