What is x when 68 divided by x equals 13?

To find the answer, just divide the dividend by the quotient: 68 ÷ 13 = 5.2307692307692

To prove this, let's compute 68 divided by 5.2307692307692: $\frac{68}{5.2307692307692} = 13$

How does it work?

Asking what the value of x could be when 68 divided by x gives a result of 13, is equivalent to solving the following equation:

$\frac{68}{x} = 13$

Multiply both sides by x: $\frac{68 x}{x} = 13 x$
$\frac{68 x}{x}$ is equivalent to $\frac{x}{x} \times 68$ , which simplifies to $1 \times 68$ (or just $68$ ).
Thus, the equation becomes: $68 = 13 x$
To find x, divide both sides by 13: $\frac{68}{13} = \frac{13 x}{13}$
Which gives, after simplification: $5.2307692307692 = x$ (or $x = 5.2307692307692$ )

So, if the dividend is 68 and the quotient is 13, the divisor is 5.2307692307692.
