Step-by-Step Examples
Example 1: 30% of 50%
Step 1: Convert percentages to decimals: 30% = 0.30, 50% = 0.50
Step 2: Divide: 0.30 ÷ 0.50 = 0.60
Step 3: Convert back to percentage: 0.60 × 100 = 60%
Answer: 30% is 60% of 50%
Example 2: 15% of 80% of 200
Step 1: First calculate 15% of 80%: (15 ÷ 80) × 100 = 18.75%
Step 2: Then 18.75% of 200: (18.75 ÷ 100) × 200 = 37.5
Answer: 15% of 80% of 200 = 37.5
Example 3: 25% of 75% of 40%
Step 1: 25% of 75%: (25 ÷ 75) × 100 = 33.33%
Step 2: 33.33% of 40%: (33.33 ÷ 40) × 100 = 83.33%
Answer: 25% of 75% of 40% = 83.33%
