What is x when 25 divided by x equals 19?

To find the answer, just divide the dividend by the quotient: 25 ÷ 19 = 1.3157894736842

To prove this, let's compute 25 divided by 1.3157894736842: $\frac{25}{1.3157894736842} = 19$

How does it work?

Asking what the value of x could be when 25 divided by x gives a result of 19, is equivalent to solving the following equation:

$\frac{25}{x} = 19$

Multiply both sides by x: $\frac{25 x}{x} = 19 x$
$\frac{25 x}{x}$ is equivalent to $\frac{x}{x} \times 25$ , which simplifies to $1 \times 25$ (or just $25$ ).
Thus, the equation becomes: $25 = 19 x$
To find x, divide both sides by 19: $\frac{25}{19} = \frac{19 x}{19}$
Which gives, after simplification: $1.3157894736842 = x$ (or $x = 1.3157894736842$ )

So, if the dividend is 25 and the quotient is 19, the divisor is 1.3157894736842.
