What is x when 27 divided by x equals 12?

To find the answer, just divide the dividend by the quotient: 27 ÷ 12 = 2.25

To prove this, let's compute 27 divided by 2.25: $\frac{27}{2.25} = 12$

How does it work?

Asking what the value of x could be when 27 divided by x gives a result of 12, is equivalent to solving the following equation:

$\frac{27}{x} = 12$

Multiply both sides by x: $\frac{27 x}{x} = 12 x$
$\frac{27 x}{x}$ is equivalent to $\frac{x}{x} \times 27$ , which simplifies to $1 \times 27$ (or just $27$ ).
Thus, the equation becomes: $27 = 12 x$
To find x, divide both sides by 12: $\frac{27}{12} = \frac{12 x}{12}$
Which gives, after simplification: $2.25 = x$ (or $x = 2.25$ )

So, if the dividend is 27 and the quotient is 12, the divisor is 2.25.
