What is x when 27 divided by x equals 42?

To find the answer, just divide the dividend by the quotient: 27 ÷ 42 = 0.64285714285714

To prove this, let's compute 27 divided by 0.64285714285714: $\frac{27}{0.64285714285714} = 42$

How does it work?

Asking what the value of x could be when 27 divided by x gives a result of 42, is equivalent to solving the following equation:

$\frac{27}{x} = 42$

Multiply both sides by x: $\frac{27 x}{x} = 42 x$
$\frac{27 x}{x}$ is equivalent to $\frac{x}{x} \times 27$ , which simplifies to $1 \times 27$ (or just $27$ ).
Thus, the equation becomes: $27 = 42 x$
To find x, divide both sides by 42: $\frac{27}{42} = \frac{42 x}{42}$
Which gives, after simplification: $0.64285714285714 = x$ (or $x = 0.64285714285714$ )

So, if the dividend is 27 and the quotient is 42, the divisor is 0.64285714285714.
