Answer:
1. 38%
2. 600 respondents
3. 12 learners
4. 336 bottles
5. 12% unripe mangoes
Step-by-step explanation:
1. 9,500 ÷ 25,000 = 0.38 into percent = 38%
2. 252 ÷ 0.42 (42%) = 600
3. 80 × 0.15 (15%) = 12
4. 100% - 16% = 84%
400 × 84% = 336
Or this:
400 × 0.16(16%) = 64
400 - 64 = 336
5. 350 ÷ 42 = 0.12 into percent = 12%
