A special application of proper fractions is the use of percentage.  While speaking of a 30% raise in pay, one is actually denoting a fractional part of a whole, 30/100.  A word percent means "hundredth;" therefore, 30% is based on the whole value being 100%. Therefore, to perform arithmetic operations, the 30% expression is represented as a decimal equivalent (0.30) rather than using the % form.
