A certain rate per cent; the allowance, duty, rate of interest, discount, or commission, on a hundred.
A part of a whole, expressed in hundredths. For example 99 percent of a pie equals 99 pieces of the pie.
A fraction expressed in hundredths. If 50% of people are male, then 50 out of every 100 people are male. But beware of surveys with small sample sizes. If 2 people were surveyed, and 1 was male, that's still 50%. As a rough guide, if the sample is less than about 20, don't quote percentage figures unless you're comparing two groups of people.
