- Tuesday, Sept 2 Lesson 6.1.7 Rate and Ratio Problems
- Slide 33
- Objective: To solve rate and ratio problems.
- Slide 34
- Rate and Ratio Problems You can use bar diagrams, rate or ratio
tables, or equivalent ratios to solve rate and ratio problems.
- Slide 35
- Rate and Ratio Problems
- Slide 36
- Method 1 Make a rate table. A rate table is the same as a ratio
table.
- Slide 37
- Rate and Ratio Problems Like Gel2 Total3150
- Slide 38
- Rate and Ratio Problems Like Gel22 Total33150
- Slide 39
- Rate and Ratio Problems Like Gel22 Total33150 x ?
- Slide 40
- Rate and Ratio Problems Like Gel22 Total33150 x 50
- Slide 41
- Rate and Ratio Problems Like Gel22100 Total33150 x 50
- Slide 42
- Rate and Ratio Problems Method 2 Set up equivalent rates or
ratios. Rule When setting up equivalent rates or ratios, always
include units.
- Slide 43
- Rate and Ratio Problems Rule When setting up equivalent rates
or ratios, always include units. In the above problem, what are our
units?
- Slide 44
- Rate and Ratio Problems ? gel ? gel ? total = ? total
- Slide 45
- Rate and Ratio Problems 2 gel ? gel 3 total = 150 total
- Slide 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 total 2 x 150 = 300
- Slide 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
- Slide 48
- Rate and Ratio Problems 2 ? 3 = 1502 x 150 = 300 3 = 100 100
students would prefer gel toothpaste.
- Slide 49
- Rate and Ratio Problems What are our units?
- Slide 50
- Rate and Ratio Problems What are our units? ? Lucas texts ?
Lucas texts ? Sister texts = ? Sister texts
- Slide 51
- Rate and Ratio Problems What are our units? 3 Lucas texts 18
Lucas texts 4 Sister texts = ? Sister texts Whats next?
- Slide 52
- Rate and Ratio Problems What are our units? 3 Lucas texts 18
Lucas texts 4 Sister texts = ? Sister texts 4 x 18 = 72 3 = 24 His
sister sent 24 texts.
- Slide 53
- Rate and Ratio Problems Do this on your own.
- Slide 54
- Rate and Ratio Problems 120 miles ? miles 3 hours = 5 hours 120
x 5 = 600 3 = 200 He drove 200 miles in 5 hours.
- Slide 55
- Rate and Ratio Problems Do this on your own.
- Slide 56
- Rate and Ratio Problems 3 science ? science 20 total = 400
total 3 x 400 = 1200 20 = 60 60 out of 400 students would choose
science.
- Slide 57
- Rate and Ratio Problems A Clydesdale drinks 120 gallons of
water every 6 days. At this rate, how many gallons of water does a
Clydesdale drink in 8 days? Do this on your own.
- Slide 58
- Rate and Ratio Problems A Clydesdale drinks 120 gallons of
water every 6 days. At this rate, how many gallons of water does a
Clydesdale drink in 8 days? 120 gallons ? gallons 6 days = 8 days
120 x 8 = 960 6 = 160 They would 160 gallons in 8 days.
- Slide 59
- Rate and Ratio Problems Out of 20 students surveyed, 13 have a
dog. Based on these results, predict how many of the 300 students
in the school have a dog. Do this on your own.
- Slide 60
- Rate and Ratio Problems Out of 20 students surveyed, 13 have a
dog. Based on these results, predict how many of the 300 students
in the school have a dog. 13 dog ? dog 20 total = 300 total 13 x
300 = 3900 20 = 195 195 would have dogs.
- Slide 61
- Rate and Ratio Problems The Millers drove 105 miles on 4
gallons of gas. At this rate, how many miles can they drive on 6
gallons of gas? Do this on your own.
- Slide 62
- Rate and Ratio Problems The Millers drove 105 miles on 4
gallons of gas. At this rate, how many miles can they drive on 6
gallons of gas? 105 miles ? miles 4 gallons = 6 gallons 105 x 6 =
630 4 = 157.5 They would travel 157.5 miles on 6 gallons.
