There are usually 2 if not 3 questions on both Level 1 and Level 2 Numeracy papers; this is then a crucial skill.
1. Understand that ratios can be simplified in the same way as fractions. 2. Use ratios directly to find 'parts' in a drink, a mix of cement etc. 3. Use 'recipes' or 'menus' to convert amounts given for 4 people to 6, 8, etc. 4. To understand that the scale on a map is a ratio - to convert from the map to real life and backwards.
EXAMPLES 1. A worksheet showing how to cancel fractions will be given.
2. Ratio is given A boy mixes a drink one part of squash to three parts of water. How much squash will he need for 2 litres of the drink?
Method a. Draw a bottle - label the two different components You have 1 part of squash 3 parts of water ________________ 4 parts altogether
b. Find out what each part is worth Divide 2 litres by 4 Change 2 litres into 2000 millilitres
c. The answer is 1 part is worth 2000/4 = 500ml
d. Draw in your diagram squash =500ml (1 part), water =1500ml (3 parts)
