Answer: There is no one specific formula

Step-by-step explanation:

The math to determine a percentage is to divide the numerator (the number on top of the fraction) by the denominator (the number on the bottom of the fraction), then multiply the answer by 100. For example, the fraction 6/12 turns into a decimal like this: 6 divided by 12 (which equals . 5) times 100 equals 50 percent

Let me start with the second screenshot :-
To find the scale factor you have to enlarge/ dilate A to get B you have a given side so assume that all sides are dilated to the same extent
: . $1 \frac{1}{2} / \frac{3}{4} = 2
$

Thus one can say m would be
$\frac{1}{2} * 2 = 1$

And N would be
$\frac{5}{6} * 2 = \frac{10}{6}$
