Rate and Ratio Problems
Rate and Ratio ProblemsObjective: To solve rate and ratio problems.
Rate and Ratio Problems You can use bar diagrams, rate or ratio tables, or equivalent ratios to solve rate and ratio problems. Rate and Ratio Problems
Rate and Ratio ProblemsMethod 1
Make a rate table.
A rate table is the same as a ratio table.

Method 2
Set up equivalent rates or ratios.
Rule When setting up equivalent rates or ratios, always include units. Rate and Ratio Problems
Rule When setting up equivalent rates or ratios, always include units.
In the above problem, what are our units? Rate and Ratio Problems
? gel ? gel ? total = ? total
Rate and Ratio Problems
2 gel ? gel 3 total = 150 total
Rate and Ratio Problems
To Solve Rate and Ratio Problems by Cross Multiplying.Step 1 Multiply across the rate or ratio. 2 gel ? gel3 total = 150 total 2 x 150 = 300
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
Rate and Ratio Problems
2 ? 3 = 1502 x 150 = 300 3 = 100
100 students would prefer gel toothpaste. Rate and Ratio Problems

4 x 18 = 72 3 = 24
His sister sent 24 texts.Rate and Ratio Problems

120 miles ? miles 3 hours = 5 hours
120 x 5 = 600 3 = 200
He drove 200 miles in 5 hours. Rate and Ratio Problems
Do this on your own. 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. Rate and Ratio ProblemsA 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.
Rate and Ratio ProblemsA 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.
Rate and Ratio ProblemsOut 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.
Rate and Ratio ProblemsOut 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.
Rate and Ratio ProblemsThe 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.
Rate and Ratio ProblemsThe 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.
