Do Now

- Nancy earns 180 in 20 hours. What is her unit

rate of her earnings? - William can pack 60 toys in 4 hours. What is his

unit rate with which he packs toys? - 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?

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?

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?

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.

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?

Independent Practice

- You will have no more than 30 minutes to work on

your independent practice. - Independent practice work is to be done quietly

or with 6 in voice if you need to work with a

partner. - We will review answers as you are working the

problems.

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.
