What is x when 79 divided by x equals 86?

To find the answer, just divide the dividend by the quotient: 79 ÷ 86 = 0.91860465116279

To prove this, let's compute 79 divided by 0.91860465116279: $\frac{79}{0.91860465116279} = 86$

How does it work?

Asking what the value of x could be when 79 divided by x gives a result of 86, is equivalent to solving the following equation:

$\frac{79}{x} = 86$

Multiply both sides by x: $\frac{79 x}{x} = 86 x$
$\frac{79 x}{x}$ is equivalent to $\frac{x}{x} \times 79$ , which simplifies to $1 \times 79$ (or just $79$ ).
Thus, the equation becomes: $79 = 86 x$
To find x, divide both sides by 86: $\frac{79}{86} = \frac{86 x}{86}$
Which gives, after simplification: $0.91860465116279 = x$ (or $x = 0.91860465116279$ )

So, if the dividend is 79 and the quotient is 86, the divisor is 0.91860465116279.
