Father of the Bride The “Superfluous” Buns
Equivalent Ratios: Table • George Banks (Steve Martin) is buying packages of hot dogs that sell 8 hot dogs in a package and 12 buns in a package. If he buys 3 packages of hot dogs and 2 packages of buns, he would not have to remove the “superfluous” buns. Fill in the table to show other ways he could buy hot dogs and buns without breaking open the package.

Equivalent Ratios: Table • A class has 2 girls for every 3 boys. Complete the table to show 6 different representations of the class but all with the same ratio of girls and boys.
Ratios and Representations: Double Number Lines • Planes 1 2 3 4 5 6 7 8 9 10 11 12 • People 200 800 1600 2400 • If 4 planes are needed to carry 800 passengers, how many planes are needed to carry 1600 passengers? • What is the ratio of planes to people? • What is ratio of people to planes? • How many people can be carried on 12 planes? • How many people can be carried on 10 planes?
Ratios and Representations • Double Number Line Diagram: • It takes 10 spools of yarn to make 15 blankets. How many spools of yarn would it take to make 6 blankets? Make a double number line to show the answer.
Ratios and Representations • It takes 10 spools of yarn to make 15 blankets. How many spools of yarn would it take to make 6 blankets? • Blankets 0 15 • Yarn 0 10
Ratios and Representations • Find the GCF of 15 and 10 and use the GCF to determine how many increments need to be made on the line. The GCF is 5. • Blankets 0 15 • Yarn 0 10
Ratios and Representations • Write the new increments on the number line. • Blankets 0 3 6 9 12 15 • Yarn 0 2 4 6 8 10
Ratios and Representations • Solve: It takes 10 spools of yarn to make 15 blankets. How many spools of yarn would it take to make 6 blankets? • Blankets 0 3 6 9 12 15 • Yarn 0 2 4 6 8 10 • 6 blankets means you will need 4 spools of yarn. • What is the ratio of blankets to yarn? • What is the ratio of yarn to blankets? • About how many blankets can you make with 1 spool of yarn?
Ratios and Representations: Tape Diagrams • For every 3 cars in a parking lot, there is one truck. Draw a picture to represent the ratio? To represent with a tape diagram, just use lines to represent the vehicles, like this:
Ratios and Representations: Tape Diagrams • For every 3 cars in a parking lot, there is one truck. Draw a picture to represent the ratio.
Ratios and Representations: Tape Diagrams • For every 3 cars in a parking lot, there is one truck. Draw a picture to represent the ratio.
Ratios and Representations: Tape Diagrams • The top line represents cars in a parking lot and the bottom line represents the trucks in a parking lot.
Ratios and Representations: Tape Diagrams • How many cars are in the lot if there is a total of 40 trucks in the lot?
Ratios and Representations: Tape Diagrams • How many trucks are in the lot if there is a total of 300 cars in the lot?
