Scale Drawing/ModelUsed to represent objects too large or too small to be drawn or built in actual size
All measurements are proportional ? What does proportional mean again?

ScaleRatio that compares the measurements of the drawing (1st) to the actual measurements (2nd)

Using Proportions!The length of a football field is 120 yards. The scale is 1 in = 20 yd. What is the length of the model football field?
Step one: Write the scale as a ratio.Step two: Fill in what you know. Place a variable (x) for what you don’t know. Match up all units!
Step three: cross multiply and solve for the variable (x).

Another Example:The length of a model airplane is 11.6 inches. The scale is 2 inches for every 15 feet in real life.
What is actual length of the airplane?

Another Example:A scooter is 3.5 feet long. Find the length of a
scale model of the scooter if the scale is 1 inch = 24 inches.
hint= you must convert ft to inches. (12 inches = 1 foot)

Scale FactorA scale written as a ratio without unitsTells how much bigger the actual thing is
Step one: Make both units the sameStep two: Now you can leave off the units
Ex: 1 inch : 3 feet12 inches = 1 foot…… so …… 3(12) = 36 inches.
1 : 36 … this means the second number is 36 times bigger than the first.

Find the scale factor! And then find out how much bigger it is?
Ex: 2 cm to 10 m
Ex: 6 inches to 1 foot
Ex: 2 inches : 15 feet
