Q. How do I write a percentage, ex 70% and decimal 2.4 in a formal paper: number or written words?

Answer

The number of the percentage should be written as a number.  Whether to write out the word "percent" depends on the context- whether it is scientific or not.  If you are writing a science paper, write 70%, but if the paper is for, say, a business class, write 70 percent.

Decimals have no special rules, just write them out as numbers- 2.4 kilograms.

For more practice writing numbers, see Purdue OWL Writing Numbers.
