1. Test Review
If a person drives 60 1/8 miles in 1 3/4 hours, compute the unit rate as the complex fraction.
Questions to consider
How is this fraction related to a ratio? Is there any difference? What elements are we using to explain our rate?
Solve this using a mathematical model in groups. Be prepared to discuss your model with your class.

2. Standard versus Non Standard Measurement
Remembering the day we went outside and counted our steps in terms of Mississippi’s what did we learn?
Why are standard measurements important?
What problems can arise using non standard measurements?

3. Converting from standard to metric
A Train is moving at 60 MPH. Please convert to the metric system and express the rate in Kilometers per hour.
Hint there are 2.54 centimeters in an inch.

4. A ratio is a comparison of one quantity to another.
6.RP Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.
Ratios
What is a ratio?
A ratio is a comparison of one quantity to another.
For example if I were baking a cake and needed to have one part sugar to four parts flour the ratio would be 1:4 or ¼.
DON’T CONFUSE FRACTIONS WITH RATIOS

5. Example conversion.
Convert the following ratios to fractions decimals and percents.
3:2 A 3:2 ratio is equal to the fraction 3/5.
3/5 Divide the denominator into the numerator to get the decimal.
3/5 = .6 (.6 is six tenths or 60 hundredths therefore it is 60%).
3/5 = .6 = 60%
