Title: Do Now

1
Do Now
1. Nancy earns 180 in 20 hours. What is her unit
rate of her earnings?
2. William can pack 60 toys in 4 hours. What is his
unit rate with which he packs toys?
3. There are 90 students in 3 classes. What is the
unit rate of students per class?

Review
• A ratio is the comparison of two numbers or
measures that have the same unit.
• Ratio of girls to boys in a class 16 girls to 15
boys
• Ratio of wins to losses for Pelicans 34 wins to
48 losses

Review
• A Rate is a ratio between two quantities of
different units.
• 110 miles in 2 hours
• Travel 240 miles on 15 gallons of gas

Review
• Unit rate is the ratio of two measurements in
which the denominator is 1.
• When two ratios are equal, it is called a
proportion.
• You solve for a unit rate by setting up a
proportion in which the denominator is 1 and
solving for the unknown.
• 110 miles in 2 hours How many miles traveled in
1 hour?
• 110 miles / 2 hours T miles / 1 hour
• Solve for the unknown T Miles traveled in 1
hour
• Cross multiple
• 110 X 1 T X 2
• 110 2T
• 110 / 2 2T / 2
• 55 T
• 55 miles traveled in 1 hour

Lesson
• Objective Compute unit rate of fractions for
ratios of lengths, areas, time, and other
quantities measured in like and different units
with 80 or greater accuracy.
• How does the objective relate to our review of
ratio, rate, and unit rate?

6
Lesson
• Compute unit rate of fractions
• Step 1 Identify the two items.
• Step 2 Set up a proportion where your
identified two items equals and unknown in the
numerator and a 1 in the denominator.
• Step 3 Solve for the unknown.
• Step 4 Write out answer in simplest form using
the correct units.
• Sophia used 1/3 of an ounce of cheese to make
1/12 of a pound of pizza dough. How many ounces
of cheese are needed to make a pound of pizza
dough?

7
Guided Practice
• 1) Jackson eats 1/4 part of a banana in 1/2
minute. How much time he will need to eat full
banana?

8
Guided Practice
• 2) Mike ran 1/2 mile in each 1/7 of an hour
compute the unit rate (miles per hour) as the
complex fraction.

9
Guided Practice
• 3) Mary made 1/5 of a batch of cookies in 1/10 of
an hour. How many batches of cookies can she make
in one hour?

10
Independent Practice
• You will have no more than 30 minutes to work on
• Independent practice work is to be done quietly
or with 6 in voice if you need to work with a
partner.

Exit Ticket
• Addison plays 1/2 of a song in 1/8 of a minute.
How many minutes will he need to play a full
song?
• Joey fills 1/5 of a toffee box in 1/25 of
a minute. How much time will he take to fill a
toffee box?
• Claire power walks 1/9 of a mile in 1/54 of an
hour. Compute the unit rate as the complex
fraction.
