What is x when 30 divided by x equals 47?

To find the answer, just divide the dividend by the quotient: 30 ÷ 47 = 0.63829787234043

To prove this, let's compute 30 divided by 0.63829787234043: $\frac{30}{0.63829787234043} = 47$

How does it work?

Asking what the value of x could be when 30 divided by x gives a result of 47, is equivalent to solving the following equation:

$\frac{30}{x} = 47$

Multiply both sides by x: $\frac{30 x}{x} = 47 x$
$\frac{30 x}{x}$ is equivalent to $\frac{x}{x} \times 30$ , which simplifies to $1 \times 30$ (or just $30$ ).
Thus, the equation becomes: $30 = 47 x$
To find x, divide both sides by 47: $\frac{30}{47} = \frac{47 x}{47}$
Which gives, after simplification: $0.63829787234043 = x$ (or $x = 0.63829787234043$ )

So, if the dividend is 30 and the quotient is 47, the divisor is 0.63829787234043.
