9. Which of these decimals equals one-half of one percent?
Answer: C
0.005 equals one-half of one percent.
One-half of one percent is calculated as 0.5% divided by 100, which simplifies to 0.005 in decimal form.
A) 0.0005
0.0005 represents one-thousandth, which is significantly less than one-half of one percent. This value does not correspond to the correct decimal representation of the given percentage.
B) 0.05
0.05 equates to five percent, which is much higher than one-half of one percent. Therefore, this option is also incorrect for the question posed.
C) 0.005
0.005 is the correct value representing one-half of one percent. It is derived from the calculation of 0.5% divided by 100, confirming its accuracy as the answer.
D) 0.5
0.5 corresponds to fifty percent, which is far greater than one-half of one percent. This option is incorrect as it does not represent the specified fraction of a percent.
Conclusion
The correct answer, 0.005, accurately reflects one-half of one percent, while the other options represent values that are either too high or too low relative to the specified percentage. This demonstrates the importance of precise calculations when dealing with percentages and their decimal equivalents.
