How to Make Them Yourself Circle Graphs How to Make Them Yourself First, put your data into a table, then add up all the values to get a total: Next, divide each value by the total and multiply by 100 to get a percent: Comedy Action Romance Drama SciFi TOTAL 4 5 6 1 20 4/20 = 20% 5/20 = 25% 6/20 = 30% 1/20 = 5% 100%

Percent of a Number (Review) We can also use the percent to help us find the missing part or the whole. Example 1: If there are 20 coins in the collection, find 25% of the total coins. Example 2: If 80% of the collection is 20 coins, how many coins are in the collection?

Example 1: If there are 20 coins in the collection, find 25% of the total coins. Step One: Identify which parts of the proportion you have. Step Two: Solving for the missing value by multiplying or dividing both the numerator and denominator by the same nonzero number. 25 % of the total collection is 5 coins. 25% Part Whole Percent 100 = 20 coins 5 coins ÷ 5 ? 20 coins 25 100 = ÷ 5

Example 2: If 80% of the collection is 20 coins, how many coins are in the collection? Step One: Identify which parts of the proportion you have. Step Two: Solving for the missing value by multiplying or dividing both the numerator and denominator by the same nonzero number. If 80% of the collection is 20 coins, there is 25 coins in the collection. 80% 20 coins Part Whole Percent 100 = ÷ 4 20 coins ? 80 100 = 25 coins ÷ 4
