# Equivalent Ratios of 31.2:21.2

Equivalent ratios or equal ratios are two ratios that express the same relationship between numbers as we covered in our tutorial on scaling up ratios. You can use the equivalent ratio calculator to solve ratio and/or proportion problems as required by entering your own ratio to produce a table similar to the "Equivalent Ratios of 31.2:21.2 table" provided below. This ratio table provides an increasingly list of ratios of the same proportions where the numerator and denominator are a direct multiplication of the multiplying value (mx). Ratio tables are very useful in math for calculating and comparing equivalent ratios, although most will likely use a ratio calculator to calculate equivalent ratios, it is also useful to have a ratio table where you can quickly cross reference associated ratios, particularly when working with complex math equations to resolve advanced math problems or physics problems. As a useful reference, we have included a table which provides links to the associated ratio values for the ratio 31.2:21.2, for example 31.2.1:21.2, 31.2:21.2.1, 31.2.1:21.2.2 and so on. We hope you will find these quick reference ratio tables useful as you can print and email them to yourself to aid your learning or a useful learning aide when teaching ratios to math students.
