Further explanation
Comparison is an effort to compare two or more objects in terms of shape or size, or number
Proportional Comparisons are comparisons of two or more numbers where one number increases, the other numbers also increase
Can be formulated
[tex]\frac{x1}{y1}=\frac{x2}{y2}[/tex]
so that if:
x = 2
then
[tex]y=\frac{y}{x}\times\:2[/tex]
While the reversal value comparison is the comparison of two or more numbers where one number increases, the other number decreases in value
Can be formulated
[tex]\frac{x1}{y2}=\frac{x2}{y1}[/tex]
so that if:
x = 2
then
[tex]y=\frac{x}{y}\times\:2[/tex]
