  2. 2. Ratio Definition: A ratio compares numbers in a set order. Example: The ratio of men to women in the green box is 3:1. The ratio of women to men in the green box is 1:3.
  3. 3. Rate Definition: Rates compare things that are measured differently. Example: A woman walks 5km (distance) in 1 hour (time). This is written 5km / h.
  4. 4. Scale Definition: Scale is a ratio of the size of something compared to the size of something else. Example: This toy car is 4cm long. The real car is 400cm long. The scale is 4:400. This is the same as 1:100.
  5. 5. Scale Drawing Definition: A drawing where all parts are a certain amount smaller than the real thing. Example: In this drawing of a horse, all parts of the drawing are 10 times smaller than the real horse.
  6. 6. Fraction Definition: A part of a whole. Example: The whole pizza below has 4 slices. Someone has taken 1 slice. Three slices are left on the plate. The fraction of the whole pizza that is on the plate is ¾.
  7. 7. Equivalent Definition: The same as something else. Example: The ratio of circle A that is shaded is 1:2. The ratio of circle B that is shaded is 2:4. 1:2 is equivalent to 2:4. Circle A Circle B
  8. 8. Solve Definition: To find out something new. Example: Solve the equation to find y. 2 + y = 3. -2 -2 y = 1 We solved this equation and found that y = 1.
  9. 9. Problem Definition: Something that we need to find an answer for. Example: 2 cans of coke cost $2. How much does one can of coke cost? This is a problem. Can you find the answer? $2 ?
  10. 10. Receive Definition: To get something. Example: Bob will receive $100 for the work he is doing in the garden.
  11. 11. Distance Definition: How far it is from one point to another. Example: The distance from Sydney to Brisbane is about 1000km.
  12. 12. Floor Plan Definition: A drawing of a building of the floor of a building which is done to scale. Example: This floor plan shows a house with three bedrooms.
