What is x when 27 divided by x equals 9?

To find the answer, just divide the dividend by the quotient: 27 ÷ 9 = 3

To prove this, let's compute 27 divided by 3: $\frac{27}{3} = 9$

How does it work?

Asking what the value of x could be when 27 divided by x gives a result of 9, is equivalent to solving the following equation:

$\frac{27}{x} = 9$

Multiply both sides by x: $\frac{27 x}{x} = 9 x$
$\frac{27 x}{x}$ is equivalent to $\frac{x}{x} \times 27$ , which simplifies to $1 \times 27$ (or just $27$ ).
Thus, the equation becomes: $27 = 9 x$
To find x, divide both sides by 9: $\frac{27}{9} = \frac{9 x}{9}$
Which gives, after simplification: $3 = x$ (or $x = 3$ )

So, if the dividend is 27 and the quotient is 9, the divisor is 3.
