What is x when 49 divided by x equals 51?

To find the answer, just divide the dividend by the quotient: 49 ÷ 51 = 0.96078431372549

To prove this, let's compute 49 divided by 0.96078431372549: $\frac{49}{0.96078431372549} = 51$

How does it work?

Asking what the value of x could be when 49 divided by x gives a result of 51, is equivalent to solving the following equation:

$\frac{49}{x} = 51$

Multiply both sides by x: $\frac{49 x}{x} = 51 x$
$\frac{49 x}{x}$ is equivalent to $\frac{x}{x} \times 49$ , which simplifies to $1 \times 49$ (or just $49$ ).
Thus, the equation becomes: $49 = 51 x$
To find x, divide both sides by 51: $\frac{49}{51} = \frac{51 x}{51}$
Which gives, after simplification: $0.96078431372549 = x$ (or $x = 0.96078431372549$ )

So, if the dividend is 49 and the quotient is 51, the divisor is 0.96078431372549.
