WebThings to remember. A ratio is a comparison of two quantities. A proportion is an equality of two ratios. To write a ratio: Determine whether the ratio is part to part or part to whole. … WebFor example, suppose we want percent differences instead of ratios in the preceding example with the pigs dataset. This is possible by modifying the reverse transformation: since the uusual reverse transformation is a ratio of the form \(r = a/b\), we have that the percentage difference between \(a\) and \(b\) is \(100(a-b)/b = 100(r-1)\).
