Transcript

  • 1. Objective Be able to divide a quantity into a given ratio
  • 2. Ratio: What does this mean? A steel alloy rod is made up of 60% iron and 40% copper. So the ratio of iron to copper is 60:40. We could simplify this to give 3:2 Ratio is used to compare the sizes of two (or more) quantities. For example: a drink is made by mixing two parts orange juice with five parts water. This relationship of 2 to 5 can be written as the ratio 2:5.
  • 3. Dividing a quantity in to a ratio
    • Divide 560kg in the ratio 3:4
    Total parts 1 part parts parts 3 + 4 = 7 560  7 = 80 3 4 3 x 80 = 240kg 4 x 80 = 320kg Divide 560kg in the ratio 3:4 is 240kg:320kg
  • 4. Time to try some!
    • £900 into the ratio 4:5
    • £200 into the ratio 3:5
    • £630 into the ratio 7:11
    • 2205kg into the ratio 8:13
    • 450 hours into the ratio 5:6:7
    • 550 lbs into the ratio 5:8:9
    £400 : £500 £75 : £125 £245 : £385 840kg : 1365kg 125h : 150h : 175h 125 lbs : 200 lbs : 225 lbs
