What is x when 9 divided by x equals 8?

To find the answer, just divide the dividend by the quotient: 9 ÷ 8 = 1.125

To prove this, let's compute 9 divided by 1.125: $\frac{9}{1.125} = 8$

How does it work?

Asking what the value of x could be when 9 divided by x gives a result of 8, is equivalent to solving the following equation:

$\frac{9}{x} = 8$

Multiply both sides by x: $\frac{9 x}{x} = 8 x$
$\frac{9 x}{x}$ is equivalent to $\frac{x}{x} \times 9$ , which simplifies to $1 \times 9$ (or just $9$ ).
Thus, the equation becomes: $9 = 8 x$
To find x, divide both sides by 8: $\frac{9}{8} = \frac{8 x}{8}$
Which gives, after simplification: $1.125 = x$ (or $x = 1.125$ )

So, if the dividend is 9 and the quotient is 8, the divisor is 1.125.
