What is x when 86 divided by x equals 53?

To find the answer, just divide the dividend by the quotient: 86 ÷ 53 = 1.622641509434

To prove this, let's compute 86 divided by 1.622641509434: $\frac{86}{1.622641509434} = 53$

How does it work?

Asking what the value of x could be when 86 divided by x gives a result of 53, is equivalent to solving the following equation:

$\frac{86}{x} = 53$

Multiply both sides by x: $\frac{86 x}{x} = 53 x$
$\frac{86 x}{x}$ is equivalent to $\frac{x}{x} \times 86$ , which simplifies to $1 \times 86$ (or just $86$ ).
Thus, the equation becomes: $86 = 53 x$
To find x, divide both sides by 53: $\frac{86}{53} = \frac{53 x}{53}$
Which gives, after simplification: $1.622641509434 = x$ (or $x = 1.622641509434$ )

So, if the dividend is 86 and the quotient is 53, the divisor is 1.622641509434.
