What is x when 15 divided by x equals 27?

To find the answer, just divide the dividend by the quotient: 15 ÷ 27 = 0.55555555555556

To prove this, let's compute 15 divided by 0.55555555555556: $\frac{15}{0.55555555555556} = 27$

How does it work?

Asking what the value of x could be when 15 divided by x gives a result of 27, is equivalent to solving the following equation:

$\frac{15}{x} = 27$

Multiply both sides by x: $\frac{15 x}{x} = 27 x$
$\frac{15 x}{x}$ is equivalent to $\frac{x}{x} \times 15$ , which simplifies to $1 \times 15$ (or just $15$ ).
Thus, the equation becomes: $15 = 27 x$
To find x, divide both sides by 27: $\frac{15}{27} = \frac{27 x}{27}$
Which gives, after simplification: $0.55555555555556 = x$ (or $x = 0.55555555555556$ )

So, if the dividend is 15 and the quotient is 27, the divisor is 0.55555555555556.
