What is x when 58 divided by x equals 66?

To find the answer, just divide the dividend by the quotient: 58 ÷ 66 = 0.87878787878788

To prove this, let's compute 58 divided by 0.87878787878788: $\frac{58}{0.87878787878788} = 66$

How does it work?

Asking what the value of x could be when 58 divided by x gives a result of 66, is equivalent to solving the following equation:

$\frac{58}{x} = 66$

Multiply both sides by x: $\frac{58 x}{x} = 66 x$
$\frac{58 x}{x}$ is equivalent to $\frac{x}{x} \times 58$ , which simplifies to $1 \times 58$ (or just $58$ ).
Thus, the equation becomes: $58 = 66 x$
To find x, divide both sides by 66: $\frac{58}{66} = \frac{66 x}{66}$
Which gives, after simplification: $0.87878787878788 = x$ (or $x = 0.87878787878788$ )

So, if the dividend is 58 and the quotient is 66, the divisor is 0.87878787878788.
