What is x when 42 divided by x equals 74?

To find the answer, just divide the dividend by the quotient: 42 ÷ 74 = 0.56756756756757

To prove this, let's compute 42 divided by 0.56756756756757: $\frac{42}{0.56756756756757} = 74$

How does it work?

Asking what the value of x could be when 42 divided by x gives a result of 74, is equivalent to solving the following equation:

$\frac{42}{x} = 74$

Multiply both sides by x: $\frac{42 x}{x} = 74 x$
$\frac{42 x}{x}$ is equivalent to $\frac{x}{x} \times 42$ , which simplifies to $1 \times 42$ (or just $42$ ).
Thus, the equation becomes: $42 = 74 x$
To find x, divide both sides by 74: $\frac{42}{74} = \frac{74 x}{74}$
Which gives, after simplification: $0.56756756756757 = x$ (or $x = 0.56756756756757$ )

So, if the dividend is 42 and the quotient is 74, the divisor is 0.56756756756757.
