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

$\frac{x1}{y1}=\frac{x2}{y2}$

so that if:

x = 2

then

$y=\frac{y}{x}\times\:2$

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

$\frac{x1}{y2}=\frac{x2}{y1}$

so that if:

x = 2

then

$y=\frac{x}{y}\times\:2$

Erik buys 2.5 pounds of cashews

each pound of cashews costs $7.70

So there is  Proportional Comparisons

1 pound = $7.70

2.5 pound = ?
