What is x when 64 divided by x equals 99?

To find the answer, just divide the dividend by the quotient: 64 ÷ 99 = 0.64646464646465

To prove this, let's compute 64 divided by 0.64646464646465: $\frac{64}{0.64646464646465} = 99$

How does it work?

Asking what the value of x could be when 64 divided by x gives a result of 99, is equivalent to solving the following equation:

$\frac{64}{x} = 99$

Multiply both sides by x: $\frac{64 x}{x} = 99 x$
$\frac{64 x}{x}$ is equivalent to $\frac{x}{x} \times 64$ , which simplifies to $1 \times 64$ (or just $64$ ).
Thus, the equation becomes: $64 = 99 x$
To find x, divide both sides by 99: $\frac{64}{99} = \frac{99 x}{99}$
Which gives, after simplification: $0.64646464646465 = x$ (or $x = 0.64646464646465$ )

So, if the dividend is 64 and the quotient is 99, the divisor is 0.64646464646465.
