What is x when 66 divided by x equals 38?

To find the answer, just divide the dividend by the quotient: 66 ÷ 38 = 1.7368421052632

To prove this, let's compute 66 divided by 1.7368421052632: $\frac{66}{1.7368421052632} = 38$

How does it work?

Asking what the value of x could be when 66 divided by x gives a result of 38, is equivalent to solving the following equation:

$\frac{66}{x} = 38$

Multiply both sides by x: $\frac{66 x}{x} = 38 x$
$\frac{66 x}{x}$ is equivalent to $\frac{x}{x} \times 66$ , which simplifies to $1 \times 66$ (or just $66$ ).
Thus, the equation becomes: $66 = 38 x$
To find x, divide both sides by 38: $\frac{66}{38} = \frac{38 x}{38}$
Which gives, after simplification: $1.7368421052632 = x$ (or $x = 1.7368421052632$ )

So, if the dividend is 66 and the quotient is 38, the divisor is 1.7368421052632.
