For the fifth sack, divide its contents into eight equal piles, giving 1}8} of a sack each. Give each chicken coop one of the 1}2} sack piles and one of the 1}8} sack piles. The idea is that it is easier to judge splitting a sack into equal piles (1}2} or 1}8}) than to divide it asymmetrically into 3}8} and 5}8} .  \nChapter 2: Ratios and percentages  \nStarter 2 (page 24)  \n288  \nExercise 2.1 (page 26)  \n1 2 : 5 2 2 : 3 3 7 : 11  \n4 3 : 13 5 4 : 5 : 7 6 3 : 4 : 6  \n7 3 : 4 : 7 8 2 : 5 9 5 : 7 : 8  \n10 £15, £20","cbCairea18zUOSb6","https://ap.wps.com/l/cbCairea18zUOSb6","pdf",3052149,1,64,"English","en",105,"# Chapter 1: Fractions, decimals and rounding\n## Starter 1 (page 1)\n## Exercise 1.1 (page 6)\n## Exercise 1.2 (page 9)\n## Exercise 1.3 (page 11)\n## Exercise 1.4 (page 14)\n## Exercise 1.5 (page 16)\n## Exercise 1.6 (page 18)\n## Review Exercise 1 (page 18)\n## Internet Challenge 1 (page 23)\n# Chapter 2: Ratios and percentages\n## Starter 2 (page 24)\n## Exercise 2.1 (page 26)\n## Exercise 2.2 (page 29)\n## Exercise 2.3 (page 30)\n## Exercise 2.4 (page 32)\n## Exercise 2.5 (page 34)\n## Review Exercise 2 (page 34)\n## Internet Challenge 2 (page 37)","[{\"question\":\"What topics are covered in these answer materials?\",\"answer\":\"The answers cover Chapter 1: Fractions, decimals and rounding, and Chapter 2: Ratios and percentages.\"},{\"question\":\"Are the answers organized by specific exercises and pages?\",\"answer\":\"Yes.
