• 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.
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?
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.
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
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%
There are 5 tennis balls and 3
basket balls in one bag. Express all
the possible ratios and then
convert to a decimal fraction and
percentage.
