Find the average of 10, 20, 35, 45, and 105. Example: 10 + 20 + 35 + 45 + 105 = 215 Step 1: Add all the quantities. 215 / 5 = 43 Step 2: Divide the total by the number of given quantities. Practice: Remember to show all your work, include if given, and NO CALCULATORS! All work and answers go on your answer sheet. Find the average of the following numbers: 11, 12, 13, 14, 15, 23, and 29 Find the average of the following numbers: 124, 456, 788, and 343 Find the average of the following numbers: 4.56, .0078, 23.45, and .9872 Percentages Percents show fractions or decimals with a denominator of 100. Always move the decimal TWO places to the right go from a decimal to a percentage or TWO places to the left to go from a percent to a decimal. .85 = 85%. .008 = .8% Examples: Part I: Finding the Percent of a Number To find the percent of a given number, change the percent to a decimal and MULTIPLY. Example: 30% of 400 30% = .30 Step 1: 400 x Step 2: .30 12000 Step 3: the digits behind the decimal in the problem and add decimal to the answer. 12000 120.00 120
