1. Be able to divide a quantity into a given ratio
Objective
Be able to divide a quantity into a given ratio

2. Ratio: What does this mean?
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.
So the ratio of iron to copper is 60:40.
We could simplify this to give 3:2
A steel alloy rod is made up of 60% iron and 40% copper.

3. Dividing a quantity in to a ratio
Divide 560kg in the ratio 3:4
Total parts
1 part
parts
3 + 4 = 7
560  7 = 80 3
3 x 80 = 240kg 4
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 £400 : £500
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
125lbs : 200lbs : 225lbs
