Which of these decimals equals one-half of one percent?

Rationale

0.005 equals one-half of one percent.

One percent is equal to 0.01 in decimal form. Therefore, one-half of one percent (0.5% or 1/2 of 1%) would be half of 0.01, which is 0.005.

A (0.0005) YOUR ANSWER

This decimal is incorrect because it represents one-twentieth of one percent, not one-half. To convert a percentage to a decimal, you divide by 100, so 0.5% is 0.005, not 0.0005.

B (0.05) YOUR ANSWER

This decimal is incorrect because it represents five percent, not one-half of one percent. To convert a percentage to a decimal, you divide by 100, so 0.5% is 0.005, not 0.05.

D (0.5) YOUR ANSWER

This decimal is incorrect because it represents fifty percent, not one-half of one percent. To convert a percentage to a decimal, you divide by 100, so 0.5% is 0.005, not 0.5.

Conclusion

In converting percentages to decimals, we divide by 100. Therefore, one-half of one percent (0.5% or 1/2 of 1%) is 0.005. The other decimals either represent values that are too large (0.05 and 0.5) or too small (0.0005) to be correct. Hence, the correct answer is 0.005.

Which of these decimals equals one-half of one percent?
