Max Maths, Year 5, Work Book, Ratio

In the Max Maths Year 5 Workbook, Practice 9 focuses on solving ratio-related word problems, a vital skill for understanding proportional relationships. Students are presented with a variety of scenarios that require them to apply their knowledge of ratio and proportion to find solutions. For instance, they are asked to calculate the total amount of fabric needed for a team of 8, given that one sports tracksuit requires 160 meters of fabric. They must also determine whether Tya has enough cocoa to make three chocolate cakes when each cake requires 30 grams and she has only 100 grams left.

Other practical applications of ratio in the workbook include mixing paint to create a specific colour, where Samir needs to maintain a ratio of 5 parts yellow to 2 parts red, and he wants to use up his 6 tins of red paint. The workbook also challenges students to understand the relationship between distance and time by comparing the running distances of Padma and Toby when their usual running time is reduced. Additionally, there are problems involving the microwave timing for multiple dessert portions, the cost of pens in cents, the price of cherries per kilogram, and the cost of cakes in a bakery. These problems are designed to enhance students' mathematical reasoning and their ability to manipulate ratios in various contexts.
