Studdy Solution
1 To find what number 0.5% 0.5\% of 8 is, use the formula:
Part=Percent100×Whole\text{Part} = \frac{\text{Percent}}{100} \times \text{Whole}
Substitute the values:
Part=0.5100×8\text{Part} = \frac{0.5}{100} \times 8
Calculate the part:
Part=0.005×8=0.04\text{Part} = 0.005 \times 8 = 0.04
So, 0.5% 0.5\% of 8 is 0.04.
