What is x when 51 divided by x equals 54?

To find the answer, just divide the dividend by the quotient: 51 ÷ 54 = 0.94444444444444

To prove this, let's compute 51 divided by 0.94444444444444: $\frac{51}{0.94444444444444} = 54$

How does it work?

Asking what the value of x could be when 51 divided by x gives a result of 54, is equivalent to solving the following equation:

$\frac{51}{x} = 54$

Multiply both sides by x: $\frac{51 x}{x} = 54 x$
$\frac{51 x}{x}$ is equivalent to $\frac{x}{x} \times 51$ , which simplifies to $1 \times 51$ (or just $51$ ).
Thus, the equation becomes: $51 = 54 x$
To find x, divide both sides by 54: $\frac{51}{54} = \frac{54 x}{54}$
Which gives, after simplification: $0.94444444444444 = x$ (or $x = 0.94444444444444$ )

So, if the dividend is 51 and the quotient is 54, the divisor is 0.94444444444444.
