What is x when 77 divided by x equals 17?

To find the answer, just divide the dividend by the quotient: 77 ÷ 17 = 4.5294117647059

To prove this, let's compute 77 divided by 4.5294117647059: $\frac{77}{4.5294117647059} = 17$

How does it work?

Asking what the value of x could be when 77 divided by x gives a result of 17, is equivalent to solving the following equation:

$\frac{77}{x} = 17$

Multiply both sides by x: $\frac{77 x}{x} = 17 x$
$\frac{77 x}{x}$ is equivalent to $\frac{x}{x} \times 77$ , which simplifies to $1 \times 77$ (or just $77$ ).
Thus, the equation becomes: $77 = 17 x$
To find x, divide both sides by 17: $\frac{77}{17} = \frac{17 x}{17}$
Which gives, after simplification: $4.5294117647059 = x$ (or $x = 4.5294117647059$ )

So, if the dividend is 77 and the quotient is 17, the divisor is 4.5294117647059.
