1. The problem involves calculating the percentage values of given numbers. 2. The formula to calculate a percentage of a number is: $$\text{Percentage value} = \frac{\text{Percentage}}{100} \times \text{Number}$$ 3. Let's calculate each percentage value step-by-step: - For 18% of 50: $$18\% \times 50 = \frac{18}{100} \times 50 = 0.18 \times 50 = 9$$ - For 7% of 25: $$7\% \times 25 = \frac{7}{100} \times 25 = 0.07 \times 25 = 1.75$$ - For 34% of 2: $$34\% \times 2 = \frac{34}{100} \times 2 = 0.34 \times 2 = 0.68$$ - For 90% of 500: $$90\% \times 500 = \frac{90}{100} \times 500 = 0.9 \times 500 = 450$$ - For 70% of 10: $$70\% \times 10 = \frac{70}{100} \times 10 = 0.7 \times 10 = 7$$ - For 3% of 400: $$3\% \times 400 = \frac{3}{100} \times 400 = 0.03 \times 400 = 12$$ - For 150 and 15, since no percentage is given, we cannot calculate a percentage value. 4. Summary of calculated values: - 18% of 50 is 9 - 7% of 25 is 1.75 - 34% of 2 is 0.68 - 90% of 500 is 450 - 70% of 10 is 7 - 3% of 400 is 12 This completes the percentage calculations for the given data.
