What is x when 17 divided by x equals 45?

To find the answer, just divide the dividend by the quotient: 17 ÷ 45 = 0.37777777777778

To prove this, let's compute 17 divided by 0.37777777777778: $\frac{17}{0.37777777777778} = 45$

How does it work?

Asking what the value of x could be when 17 divided by x gives a result of 45, is equivalent to solving the following equation:

$\frac{17}{x} = 45$

Multiply both sides by x: $\frac{17 x}{x} = 45 x$
$\frac{17 x}{x}$ is equivalent to $\frac{x}{x} \times 17$ , which simplifies to $1 \times 17$ (or just $17$ ).
Thus, the equation becomes: $17 = 45 x$
To find x, divide both sides by 45: $\frac{17}{45} = \frac{45 x}{45}$
Which gives, after simplification: $0.37777777777778 = x$ (or $x = 0.37777777777778$ )

So, if the dividend is 17 and the quotient is 45, the divisor is 0.37777777777778.
