What is x when 73 divided by x equals 9?

To find the answer, just divide the dividend by the quotient: 73 ÷ 9 = 8.1111111111111

To prove this, let's compute 73 divided by 8.1111111111111: $\frac{73}{8.1111111111111} = 9$

How does it work?

Asking what the value of x could be when 73 divided by x gives a result of 9, is equivalent to solving the following equation:

$\frac{73}{x} = 9$

Multiply both sides by x: $\frac{73 x}{x} = 9 x$
$\frac{73 x}{x}$ is equivalent to $\frac{x}{x} \times 73$ , which simplifies to $1 \times 73$ (or just $73$ ).
Thus, the equation becomes: $73 = 9 x$
To find x, divide both sides by 9: $\frac{73}{9} = \frac{9 x}{9}$
Which gives, after simplification: $8.1111111111111 = x$ (or $x = 8.1111111111111$ )

So, if the dividend is 73 and the quotient is 9, the divisor is 8.1111111111111.
