What is x when 77 divided by x equals 49?

To find the answer, just divide the dividend by the quotient: 77 ÷ 49 = 1.5714285714286

To prove this, let's compute 77 divided by 1.5714285714286: $\frac{77}{1.5714285714286} = 49$

How does it work?

Asking what the value of x could be when 77 divided by x gives a result of 49, is equivalent to solving the following equation:

$\frac{77}{x} = 49$

Multiply both sides by x: $\frac{77 x}{x} = 49 x$
$\frac{77 x}{x}$ is equivalent to $\frac{x}{x} \times 77$ , which simplifies to $1 \times 77$ (or just $77$ ).
Thus, the equation becomes: $77 = 49 x$
To find x, divide both sides by 49: $\frac{77}{49} = \frac{49 x}{49}$
Which gives, after simplification: $1.5714285714286 = x$ (or $x = 1.5714285714286$ )

So, if the dividend is 77 and the quotient is 49, the divisor is 1.5714285714286.
