# Equivalent Ratios of 1:2

Equivalent ratios or equal ratios are two ratios that express the same relationship between numbers. 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 1:2 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 1:2, for example 1.1:2, 1:2.1, 1.1:2.2 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.

## How to Calculate Ratios

When calculating equivalent ratios you must multiply or divide both numbers in the ratio. This keeps both numbers in direct relation to each other. So, a ratio of 2/3 has an equivalent ratio of 4/6: in this ratio calculation we simply multiplied both 2 and 3 by 2.

## Mathematical facts about the ratio 1:2

If you wish to express the ratio 1:2 as n to 1 then the ratio would be:

1:2 as n to 1
= 0.5 : 1

If you wish to express the ratio 1:2 as 1 to n then the ratio would be:

1:2 as 1 to n
= 1 : 2

The ratio 1:2 expressed as a fraction is [calculated using the ratio to fraction calculator]:

1:2
= 1/2

The ratio 1:2 expressed as a percentage is [calculated using the ratio to percentage calculator]:

1:2
= 50%
