What is x when 84 divided by x equals 89?

To find the answer, just divide the dividend by the quotient: 84 ÷ 89 = 0.9438202247191

To prove this, let's compute 84 divided by 0.9438202247191: $\frac{84}{0.9438202247191} = 89$

How does it work?

Asking what the value of x could be when 84 divided by x gives a result of 89, is equivalent to solving the following equation:

$\frac{84}{x} = 89$

Multiply both sides by x: $\frac{84 x}{x} = 89 x$
$\frac{84 x}{x}$ is equivalent to $\frac{x}{x} \times 84$ , which simplifies to $1 \times 84$ (or just $84$ ).
Thus, the equation becomes: $84 = 89 x$
To find x, divide both sides by 89: $\frac{84}{89} = \frac{89 x}{89}$
Which gives, after simplification: $0.9438202247191 = x$ (or $x = 0.9438202247191$ )

So, if the dividend is 84 and the quotient is 89, the divisor is 0.9438202247191.
