What is x when 76 divided by x equals 42?

To find the answer, just divide the dividend by the quotient: 76 ÷ 42 = 1.8095238095238

To prove this, let's compute 76 divided by 1.8095238095238: $\frac{76}{1.8095238095238} = 42$

How does it work?

Asking what the value of x could be when 76 divided by x gives a result of 42, is equivalent to solving the following equation:

$\frac{76}{x} = 42$

Multiply both sides by x: $\frac{76 x}{x} = 42 x$
$\frac{76 x}{x}$ is equivalent to $\frac{x}{x} \times 76$ , which simplifies to $1 \times 76$ (or just $76$ ).
Thus, the equation becomes: $76 = 42 x$
To find x, divide both sides by 42: $\frac{76}{42} = \frac{42 x}{42}$
Which gives, after simplification: $1.8095238095238 = x$ (or $x = 1.8095238095238$ )

So, if the dividend is 76 and the quotient is 42, the divisor is 1.8095238095238.
