What is x when 90 divided by x equals 53?

To find the answer, just divide the dividend by the quotient: 90 ÷ 53 = 1.6981132075472

To prove this, let's compute 90 divided by 1.6981132075472: $\frac{90}{1.6981132075472} = 53$

How does it work?

Asking what the value of x could be when 90 divided by x gives a result of 53, is equivalent to solving the following equation:

$\frac{90}{x} = 53$

Multiply both sides by x: $\frac{90 x}{x} = 53 x$
$\frac{90 x}{x}$ is equivalent to $\frac{x}{x} \times 90$ , which simplifies to $1 \times 90$ (or just $90$ ).
Thus, the equation becomes: $90 = 53 x$
To find x, divide both sides by 53: $\frac{90}{53} = \frac{53 x}{53}$
Which gives, after simplification: $1.6981132075472 = x$ (or $x = 1.6981132075472$ )

So, if the dividend is 90 and the quotient is 53, the divisor is 1.6981132075472.
