Proportion Proportion is the relationship between quantities: the relationship between two or more amounts or numbers, or between the parts of a whole. An example for how to work out proportion is this: First the simplify method: 6:12= 1:2 1. Divide 6 and 12 by 6 and that’s your answer.] The unitary method An example is: 6 bars of chocolate costs £1.80. How much does one bar cost? 6 bars= £1.80 Divide 6 and £1.80 by 6 = 30p
Best Buy Do you want to know how to buy the cheapest thing!! Then look below and flow with the method. 6 £1.20 48 £4.00 This is chocolate syrup 20 for £ 40.00 This is chocolate syrup 5 for £ 3.00. Do the 6 packed carrots which would be: 1.20 divided by 6= £0.02 . This is how much 1 costs. 2. To find out how much the 24 packed carrots would be: 4.00 divided by 48 = £0.83 . This is how much one costs. 2. Then do 20 divided by £40.00= 20p 1. Do £3.00 divided by 5 = 60p. The best buy is the 6 packed carrots. I know some people may have thought that the 48 pack one was the best buy but sometimes they trick you so you always have to check. The best buy product is the chocolate syrup for £40.00. This is one of the prices that will trick you into buying the £3.00 one.
