What is x when 43 divided by x equals 83?

To find the answer, just divide the dividend by the quotient: 43 ÷ 83 = 0.51807228915663

To prove this, let's compute 43 divided by 0.51807228915663: $\frac{43}{0.51807228915663} = 83$

How does it work?

Asking what the value of x could be when 43 divided by x gives a result of 83, is equivalent to solving the following equation:

$\frac{43}{x} = 83$

Multiply both sides by x: $\frac{43 x}{x} = 83 x$
$\frac{43 x}{x}$ is equivalent to $\frac{x}{x} \times 43$ , which simplifies to $1 \times 43$ (or just $43$ ).
Thus, the equation becomes: $43 = 83 x$
To find x, divide both sides by 83: $\frac{43}{83} = \frac{83 x}{83}$
Which gives, after simplification: $0.51807228915663 = x$ (or $x = 0.51807228915663$ )

So, if the dividend is 43 and the quotient is 83, the divisor is 0.51807228915663.
