Name of a Number Study the example problem shaowing how to find the percent of a number. Then solve problems 1-6. Example In an after-school sports program, 70% of 400 students play soccer. How many students play soccer? You can use a model to find 70% of 400. 40 40 40 40 40 40 40 40 40 40 0% 10% 20% 30% 40% 50% 60% 70% 80% 90O% 100% The model shows 400 divided into groups of 40. Each group of 40 represents 10% of 400, so 7 groups of 40 represent 70% of 400. This means that 70% of 400 is 7.40, or 280. There are 280 students who play soccer. 201400 What is 70% written as a fraction?101400 expression that represents 70% of 400. Compare the answer to the one you got using the model. Use the fraction to write and evaluate a multiplication
