What is x when 89 divided by x equals 28?

To find the answer, just divide the dividend by the quotient: 89 ÷ 28 = 3.1785714285714

To prove this, let's compute 89 divided by 3.1785714285714: $\frac{89}{3.1785714285714} = 28$

How does it work?

Asking what the value of x could be when 89 divided by x gives a result of 28, is equivalent to solving the following equation:

$\frac{89}{x} = 28$

Multiply both sides by x: $\frac{89 x}{x} = 28 x$
$\frac{89 x}{x}$ is equivalent to $\frac{x}{x} \times 89$ , which simplifies to $1 \times 89$ (or just $89$ ).
Thus, the equation becomes: $89 = 28 x$
To find x, divide both sides by 28: $\frac{89}{28} = \frac{28 x}{28}$
Which gives, after simplification: $3.1785714285714 = x$ (or $x = 3.1785714285714$ )

So, if the dividend is 89 and the quotient is 28, the divisor is 3.1785714285714.
