What is x when 77 divided by x equals 19?

To find the answer, just divide the dividend by the quotient: 77 ÷ 19 = 4.0526315789474

To prove this, let's compute 77 divided by 4.0526315789474: $\frac{77}{4.0526315789474} = 19$

How does it work?

Asking what the value of x could be when 77 divided by x gives a result of 19, is equivalent to solving the following equation:

$\frac{77}{x} = 19$

Multiply both sides by x: $\frac{77 x}{x} = 19 x$
$\frac{77 x}{x}$ is equivalent to $\frac{x}{x} \times 77$ , which simplifies to $1 \times 77$ (or just $77$ ).
Thus, the equation becomes: $77 = 19 x$
To find x, divide both sides by 19: $\frac{77}{19} = \frac{19 x}{19}$
Which gives, after simplification: $4.0526315789474 = x$ (or $x = 4.0526315789474$ )

So, if the dividend is 77 and the quotient is 19, the divisor is 4.0526315789474.
