What is x when 54 divided by x equals 43?

To find the answer, just divide the dividend by the quotient: 54 ÷ 43 = 1.2558139534884

To prove this, let's compute 54 divided by 1.2558139534884: $\frac{54}{1.2558139534884} = 43$

How does it work?

Asking what the value of x could be when 54 divided by x gives a result of 43, is equivalent to solving the following equation:

$\frac{54}{x} = 43$

Multiply both sides by x: $\frac{54 x}{x} = 43 x$
$\frac{54 x}{x}$ is equivalent to $\frac{x}{x} \times 54$ , which simplifies to $1 \times 54$ (or just $54$ ).
Thus, the equation becomes: $54 = 43 x$
To find x, divide both sides by 43: $\frac{54}{43} = \frac{43 x}{43}$
Which gives, after simplification: $1.2558139534884 = x$ (or $x = 1.2558139534884$ )

So, if the dividend is 54 and the quotient is 43, the divisor is 1.2558139534884.
