What is x when 86 divided by x equals 89?

To find the answer, just divide the dividend by the quotient: 86 ÷ 89 = 0.96629213483146

To prove this, let's compute 86 divided by 0.96629213483146: $\frac{86}{0.96629213483146} = 89$

How does it work?

Asking what the value of x could be when 86 divided by x gives a result of 89, is equivalent to solving the following equation:

$\frac{86}{x} = 89$

Multiply both sides by x: $\frac{86 x}{x} = 89 x$
$\frac{86 x}{x}$ is equivalent to $\frac{x}{x} \times 86$ , which simplifies to $1 \times 86$ (or just $86$ ).
Thus, the equation becomes: $86 = 89 x$
To find x, divide both sides by 89: $\frac{86}{89} = \frac{89 x}{89}$
Which gives, after simplification: $0.96629213483146 = x$ (or $x = 0.96629213483146$ )

So, if the dividend is 86 and the quotient is 89, the divisor is 0.96629213483146.
