What is x when 89 divided by x equals 99?

To find the answer, just divide the dividend by the quotient: 89 ÷ 99 = 0.8989898989899

To prove this, let's compute 89 divided by 0.8989898989899: $\frac{89}{0.8989898989899} = 99$

How does it work?

Asking what the value of x could be when 89 divided by x gives a result of 99, is equivalent to solving the following equation:

$\frac{89}{x} = 99$

Multiply both sides by x: $\frac{89 x}{x} = 99 x$
$\frac{89 x}{x}$ is equivalent to $\frac{x}{x} \times 89$ , which simplifies to $1 \times 89$ (or just $89$ ).
Thus, the equation becomes: $89 = 99 x$
To find x, divide both sides by 99: $\frac{89}{99} = \frac{99 x}{99}$
Which gives, after simplification: $0.8989898989899 = x$ (or $x = 0.8989898989899$ )

So, if the dividend is 89 and the quotient is 99, the divisor is 0.8989898989899.
