What is x when 76 divided by x equals 18?

To find the answer, just divide the dividend by the quotient: 76 ÷ 18 = 4.2222222222222

To prove this, let's compute 76 divided by 4.2222222222222: $\frac{76}{4.2222222222222} = 18$

How does it work?

Asking what the value of x could be when 76 divided by x gives a result of 18, is equivalent to solving the following equation:

$\frac{76}{x} = 18$

Multiply both sides by x: $\frac{76 x}{x} = 18 x$
$\frac{76 x}{x}$ is equivalent to $\frac{x}{x} \times 76$ , which simplifies to $1 \times 76$ (or just $76$ ).
Thus, the equation becomes: $76 = 18 x$
To find x, divide both sides by 18: $\frac{76}{18} = \frac{18 x}{18}$
Which gives, after simplification: $4.2222222222222 = x$ (or $x = 4.2222222222222$ )

So, if the dividend is 76 and the quotient is 18, the divisor is 4.2222222222222.
