  1. Kindly contributed to www.skillsworkshop.org by Michael Hargreaves, Michael.Hargreaves@oldham.ac.uk The Oldham College . Adult Numeracy N1/ L1.7 Work out simple ratio and direct proportion Understand simple ratio as the number of parts, e.g. three parts to one part. Understand direct proportion as the same rate of increase or decrease, e.g. double, half. Understand relationship between simple ratio and fractions Functional Mathematics Level 1: Solve simple problems involving ratio, where one number is a multiple of the other Understand simple ratio as the number of parts, for example three parts to one part. A drink is made from juice and water in the ratio of 1:5. How many litres of drink can I make from 2 litres of juice? Understand direct proportion as the same rate of increase or decrease, for example double, half, scale up amounts of food for three times the number of people, put items in piles with twice as many items in one pile as in the other. Know how to use a simple scale to estimate distance on a road map. 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?
