5 Minute Check

1. 5 Minute Check Determine if each pair of rates or ratios are equivalent. Explain your reasoning. 1. 16 points scored in 4 games; 48 points scored in 8 games. 2. 96 words in 3 minutes;160 words in 5 minutes 3. 15 computers for 45 students; 45 computers for 135 students 4. 16 out of 28 students; 240 out of 560 students.

2. 5 Minute Check Determine if each pair of rates or ratios are equivalent. Explain your reasoning. 1. 16 points scored in 4 games; 48 points scored in 8 games. 16 points ? 48 points 4 games = 8 games 4 points6 points 1 game ≠ 1 game

32. Tuesday, Sept 2 Lesson 6.1.7 Rate and Ratio Problems

33. Rate and Ratio Problems Objective: To solve rate and ratio problems.

34. Rate and Ratio Problems You can use bar diagrams, rate or ratio tables, or equivalent ratios to solve rate and ratio problems.

35. Rate and Ratio Problems

36. Rate and Ratio Problems Method 1 Make a rate table. A rate table is the same as a ratio table.

39. Rate and Ratio Problems x ?

40. Rate and Ratio Problems x 50 x 50

41. Rate and Ratio Problems x 50 x 50

42. Rate and Ratio Problems Method 2 Set up equivalent rates or ratios. Rule – When setting up equivalent rates or ratios, always include units.

43. Rate and Ratio Problems Rule – When setting up equivalent rates or ratios, always include units. In the above problem, what are our units?

44. Rate and Ratio Problems ? gel ? gel ? total = ? total

45. Rate and Ratio Problems 2 gel ? gel 3 total = 150 total

46. Rate and Ratio Problems To Solve Rate and Ratio Problems by Cross Multiplying. Step 1 – Multiply across the rate or ratio. 2 gel ? gel 3 total = 150 total2 x 150 = 300

47. Rate and Ratio Problems To Solve Rate and Ratio Problems by Cross Multiplying. Step 2 – Divide by the remaining number. 2 gel? gel 3 total =150 total 2 x 150 = 300 ÷ 3 = 100

48. Rate and Ratio Problems 2? 3 = 150 2 x 150 = 300 ÷ 3 = 100 100 students would prefer gel toothpaste.
