What is x when 72 divided by x equals 17?

To find the answer, just divide the dividend by the quotient: 72 ÷ 17 = 4.2352941176471

To prove this, let's compute 72 divided by 4.2352941176471: $\frac{72}{4.2352941176471} = 17$

How does it work?

Asking what the value of x could be when 72 divided by x gives a result of 17, is equivalent to solving the following equation:

$\frac{72}{x} = 17$

Multiply both sides by x: $\frac{72 x}{x} = 17 x$
$\frac{72 x}{x}$ is equivalent to $\frac{x}{x} \times 72$ , which simplifies to $1 \times 72$ (or just $72$ ).
Thus, the equation becomes: $72 = 17 x$
To find x, divide both sides by 17: $\frac{72}{17} = \frac{17 x}{17}$
Which gives, after simplification: $4.2352941176471 = x$ (or $x = 4.2352941176471$ )

So, if the dividend is 72 and the quotient is 17, the divisor is 4.2352941176471.
