What is x when 50 divided by x equals 4?

To find the answer, just divide the dividend by the quotient: 50 ÷ 4 = 12.5

To prove this, let's compute 50 divided by 12.5: $\frac{50}{12.5} = 4$

How does it work?

Asking what the value of x could be when 50 divided by x gives a result of 4, is equivalent to solving the following equation:

$\frac{50}{x} = 4$

Multiply both sides by x: $\frac{50 x}{x} = 4 x$
$\frac{50 x}{x}$ is equivalent to $\frac{x}{x} \times 50$ , which simplifies to $1 \times 50$ (or just $50$ ).
Thus, the equation becomes: $50 = 4 x$
To find x, divide both sides by 4: $\frac{50}{4} = \frac{4 x}{4}$
Which gives, after simplification: $12.5 = x$ (or $x = 12.5$ )

So, if the dividend is 50 and the quotient is 4, the divisor is 12.5.
