  1. 3 5 59% Use a fraction that is close to 59%. 403 400 Round 403 to a number compatible with 5. 3 5 59% of 403 of 400 80 3 5 3 5 400 1 Multiply to find of 400. = • 1 = 240 Simplify. COURSE 3 LESSON 6-2 Estimating With Percents Estimate 59% of 403 using fractions. So, 59% of 403 is about 240. 6-2

  2. 1 5 19% Use a fraction that is close to 19%. 297 300 Round to a number that is compatible with 5. 1 5 of 300 19% of 297 60 1 5 300 1 1 5 = • = 60 Multiply to find of 300. 1 COURSE 3 LESSON 6-2 Estimating With Percents A video store rented 297 videos. The customers returned 19% of the videos late. Estimate, using fractions, how many videos were returned late. About 60 videos were returned late. 6-2

  3. 3 4 • 40 = 30 3 5 (30) = 18 students COURSE 3 LESSON 6-2 Estimating With Percents Show the numbers you use to estimate. 1. Use decimals to estimate 54% of 29. 2. Use fractions to estimate 74% of 38. 3. Estimate a 15% tip on $8.15. 4. About 60% of 27 students are in the play. 0.5 • 30 = 15 0.1(8) + 0.1(4) = 0.8 + 0.4 = $1.20 6-2
