What is x when 68 divided by x equals 18?

To find the answer, just divide the dividend by the quotient: 68 ÷ 18 = 3.7777777777778

To prove this, let's compute 68 divided by 3.7777777777778: $\frac{68}{3.7777777777778} = 18$

How does it work?

Asking what the value of x could be when 68 divided by x gives a result of 18, is equivalent to solving the following equation:

$\frac{68}{x} = 18$

Multiply both sides by x: $\frac{68 x}{x} = 18 x$
$\frac{68 x}{x}$ is equivalent to $\frac{x}{x} \times 68$ , which simplifies to $1 \times 68$ (or just $68$ ).
Thus, the equation becomes: $68 = 18 x$
To find x, divide both sides by 18: $\frac{68}{18} = \frac{18 x}{18}$
Which gives, after simplification: $3.7777777777778 = x$ (or $x = 3.7777777777778$ )

So, if the dividend is 68 and the quotient is 18, the divisor is 3.7777777777778.
