Lesson 2-3 Example Solve. SPORTS Michele and James played darts. Michele hit the bull’s-eye 7 out of 18 times. James missed the bull’s-eye 7 out of 15 times. Who hit the bull’s-eye a greater percent of the time?
Lesson 2-3 Example UnderstandRead the problem. Write what you know. Michele hit the bull’s-eye 7 out of 18 times. James did not hit the bull’s eye 7 out of 15 times.
Lesson 2-3 Example PlanPick a strategy. One strategy is to use logical reasoning.
Lesson 2-3 Example SolveWrite the fraction of Michele's hits to attempts. Write the fraction of James' misses to attempts.
Lesson 2-3 Example Write each fraction as a decimal rounded to the nearest hundredth, then as a percent. James missed the bull’s-eye 47% of the time, so he hit the bull’s-eye 100% – 47% = 53% of the time. Compare the percents. 39% < 53% James hit the bull’s-eye a greater percent of the time.
