What is x when 43 divided by x equals 28?

To find the answer, just divide the dividend by the quotient: 43 ÷ 28 = 1.5357142857143

To prove this, let's compute 43 divided by 1.5357142857143: $\frac{43}{1.5357142857143} = 28$

How does it work?

Asking what the value of x could be when 43 divided by x gives a result of 28, is equivalent to solving the following equation:

$\frac{43}{x} = 28$

Multiply both sides by x: $\frac{43 x}{x} = 28 x$
$\frac{43 x}{x}$ is equivalent to $\frac{x}{x} \times 43$ , which simplifies to $1 \times 43$ (or just $43$ ).
Thus, the equation becomes: $43 = 28 x$
To find x, divide both sides by 28: $\frac{43}{28} = \frac{28 x}{28}$
Which gives, after simplification: $1.5357142857143 = x$ (or $x = 1.5357142857143$ )

So, if the dividend is 43 and the quotient is 28, the divisor is 1.5357142857143.
