What is x when 68 divided by x equals 86?

To find the answer, just divide the dividend by the quotient: 68 ÷ 86 = 0.7906976744186

To prove this, let's compute 68 divided by 0.7906976744186: $\frac{68}{0.7906976744186} = 86$

How does it work?

Asking what the value of x could be when 68 divided by x gives a result of 86, is equivalent to solving the following equation:

$\frac{68}{x} = 86$

Multiply both sides by x: $\frac{68 x}{x} = 86 x$
$\frac{68 x}{x}$ is equivalent to $\frac{x}{x} \times 68$ , which simplifies to $1 \times 68$ (or just $68$ ).
Thus, the equation becomes: $68 = 86 x$
To find x, divide both sides by 86: $\frac{68}{86} = \frac{86 x}{86}$
Which gives, after simplification: $0.7906976744186 = x$ (or $x = 0.7906976744186$ )

So, if the dividend is 68 and the quotient is 86, the divisor is 0.7906976744186.
