What is x when 28 divided by x equals 54?

To find the answer, just divide the dividend by the quotient: 28 ÷ 54 = 0.51851851851852

To prove this, let's compute 28 divided by 0.51851851851852: $\frac{28}{0.51851851851852} = 54$

How does it work?

Asking what the value of x could be when 28 divided by x gives a result of 54, is equivalent to solving the following equation:

$\frac{28}{x} = 54$

Multiply both sides by x: $\frac{28 x}{x} = 54 x$
$\frac{28 x}{x}$ is equivalent to $\frac{x}{x} \times 28$ , which simplifies to $1 \times 28$ (or just $28$ ).
Thus, the equation becomes: $28 = 54 x$
To find x, divide both sides by 54: $\frac{28}{54} = \frac{54 x}{54}$
Which gives, after simplification: $0.51851851851852 = x$ (or $x = 0.51851851851852$ )

So, if the dividend is 28 and the quotient is 54, the divisor is 0.51851851851852.
