  1. Ratios and Proportion • Adult Numeracy N1/L2.3: Understand ratio written in the form 3:2 • Understand how to work out the number of parts in a given ratio, and the value of one part • Functional Mathematics Level 2:Understand, use and calculate ratio and proportion, including problems involving scale. • Understand ratio written in the form 3:2, sharing £60 in the ratio 3:2. • Understand how to work out the number of parts in a given ratio, and the value of 1 part. For example, the total cost for a job is £200. If the ratio between labour and materials is 5:3, how much was the labour?
