What is x when 76 divided by x equals 4?

To find the answer, just divide the dividend by the quotient: 76 ÷ 4 = 19

To prove this, let's compute 76 divided by 19: $\frac{76}{19} = 4$

How does it work?

Asking what the value of x could be when 76 divided by x gives a result of 4, is equivalent to solving the following equation:

$\frac{76}{x} = 4$

Multiply both sides by x: $\frac{76 x}{x} = 4 x$
$\frac{76 x}{x}$ is equivalent to $\frac{x}{x} \times 76$ , which simplifies to $1 \times 76$ (or just $76$ ).
Thus, the equation becomes: $76 = 4 x$
To find x, divide both sides by 4: $\frac{76}{4} = \frac{4 x}{4}$
Which gives, after simplification: $19 = x$ (or $x = 19$ )

So, if the dividend is 76 and the quotient is 4, the divisor is 19.
