What is x when 79 divided by x equals 78?

To find the answer, just divide the dividend by the quotient: 79 ÷ 78 = 1.0128205128205

To prove this, let's compute 79 divided by 1.0128205128205: $\frac{79}{1.0128205128205} = 78$

How does it work?

Asking what the value of x could be when 79 divided by x gives a result of 78, is equivalent to solving the following equation:

$\frac{79}{x} = 78$

Multiply both sides by x: $\frac{79 x}{x} = 78 x$
$\frac{79 x}{x}$ is equivalent to $\frac{x}{x} \times 79$ , which simplifies to $1 \times 79$ (or just $79$ ).
Thus, the equation becomes: $79 = 78 x$
To find x, divide both sides by 78: $\frac{79}{78} = \frac{78 x}{78}$
Which gives, after simplification: $1.0128205128205 = x$ (or $x = 1.0128205128205$ )

So, if the dividend is 79 and the quotient is 78, the divisor is 1.0128205128205.
