答案:1. 3箱苹果 * 8个苹果/箱 + 4袋苹果 * 5个苹果/袋 = 24个苹果 + 20个苹果 = 44个苹果2. 28个同学 * (3/8) = 10.5个男生(约等于11个男生),28个同学- 11个男生 = 17个女生3. 2圈 * 400米/圈 = 800米4. 28元 + 120元 - 60元 = 88元5. (长 + 宽) * 2 = (12米 + 8米) * 2 = 40米6. 12分钟 + 20分钟 = 32分钟7. 1小时 + 40分钟 + 30分钟 = 2小时10分钟8. 剩下的长度 / (1 - 2/5) = 4厘米 / (3/5) = 20 / 3 厘米(约等于6.67厘米)9. 45元 * 0.7 = 31.5元10. 10页/周 * 6周 = 60页。
