What is x when 40 divided by x equals 17?

To find the answer, just divide the dividend by the quotient: 40 ÷ 17 = 2.3529411764706

To prove this, let's compute 40 divided by 2.3529411764706: $\frac{40}{2.3529411764706} = 17$

How does it work?

Asking what the value of x could be when 40 divided by x gives a result of 17, is equivalent to solving the following equation:

$\frac{40}{x} = 17$

Multiply both sides by x: $\frac{40 x}{x} = 17 x$
$\frac{40 x}{x}$ is equivalent to $\frac{x}{x} \times 40$ , which simplifies to $1 \times 40$ (or just $40$ ).
Thus, the equation becomes: $40 = 17 x$
To find x, divide both sides by 17: $\frac{40}{17} = \frac{17 x}{17}$
Which gives, after simplification: $2.3529411764706 = x$ (or $x = 2.3529411764706$ )

So, if the dividend is 40 and the quotient is 17, the divisor is 2.3529411764706.
