Answer Key and Detailed Explanations:

1. 1/20 + 8/20 = 17/20 Find a common denominator (20) and add the fractions.

2. 3/4 0.75 is equivalent to 75/100, which simplifies to 3/4.

3. 30 (15/100) * 200 = 30

4. 62.5 mL/hour 250 mL / 4 hours = 62.5 mL/hour

5. x = 3 Subtract 5 from both sides: 2x = 6; then divide both sides by 2: x = 3

6. 40 cm² Area = length × width = 8 cm × 5 cm = 40 cm²

7. 24 inches Perimeter = 4 × side length = 4 × 6 inches = 24 inches

8. 5000 grams 1 kilogram = 1000 grams; therefore, 5 kilograms = 5000 grams

9. 39°C °C = (102°F - 32) × 5/9 = 39°C

10. 35 mg 0.5 mg/kg * 70 kg = 35 mg

11. 2/3 Simplify the fraction by dividing both numerator and denominator by their greatest common divisor (6).

12. 0.375 Divide the numerator (3) by the denominator (8).

13. 75% (150/200) * 100% = 75%

14. 48 patients If the ratio is 1:4, and there are 12 nurses, then there are 12 * 4 = 48 patients.

15. x = 5 Add 7 to both sides: 3x = 15; then divide both sides by 3: x = 5

16. 64 cm³ Volume = side³ = 4 cm × 4 cm × 4 cm = 64 cm³

17. 2000 milliliters 1 liter = 1000 milliliters; therefore, 2 liters = 2000 milliliters

18. 125 days 250 tablets / 2 tablets/day = 125 days

19. 1080 beats 72 beats/minute * 15 minutes = 1080 beats

20. x = 20 Subtract 3 from both sides: x/5 = 4; then multiply both sides by 5: x = 20

21. 3/8 There are 8 total marbles, and 3 are blue. Probability = (number of blue marbles) / (total number of marbles) = 3/8

22. 15 Add all the numbers (10+12+15+18+20=75) and divide by the number of values (5): 75/5 = 15

23. 0.025 Divide the percentage by 100.

24. 10.42 mL/minute (approximately) 500 mL / 8 hours = 62.5 mL/hour; 62.5 mL/hour / 60 minutes/hour = 1.04 mL/minute (approximately)

25. 160 hours 8 hours/day * 5 days/week * 4 weeks/month = 160 hours
