Percents and Proportions

• Percent represents a part of a whole. Remember to ask yourself if your answer makes sense. For example 50% of 120 means half of 120; 150% of 120 means over 120, in fact 120 plus an additional half.
• You can use a proportion to solve a percent problem. Set a ratio equal to an unknown out of 100.
• The number that follows the word “of” is the denominator.
