How can Ratios be expressed?
Ratios can be expressed in a numbers of ways, as a decimal, a fraction as a related comparison or as is more commonly seen a percentage. for example a ratio of 1 to 2 can be expressed as:
- 1-2 is a ratio expressed in using a hyphen, whilst this is quite commonly used it should be avoided as the hyphen also represents the minus sign in math and can be confusing in long algorithms or if using computer code or computers to process a math calculation
- 1:2 is a ratio expressed in typical math format using a colon
- 1 to 2 is a ratio expressed in written words
- 1 per 2 is a ratio expressed in written words
- 0.5 is a ratio expressed as a decimal number
- 50% is a ratio expressed as a percentage
- ½is a ratio expressed as a fraction
