6. ½% of 20 is?

Answer: A

Explanation:

½% of 20 is 1/10.

Calculating ½% of 20 yields 0.1, which can be expressed as 1/10.

A) 1/10

This option is correct because ½% of 20 is indeed 0.1, which equals 1/10. The calculation involves converting the percentage into a decimal (0.5% = 0.005) and multiplying it by 20, resulting in 0.1.

B) 1/4

This option is incorrect because 1/4 equals 0.25. Since ½% of 20 is 0.1, which is significantly less than 0.25, this choice does not reflect the correct calculation.

C) 5

This option is incorrect as 5 does not represent ½% of 20. In fact, 5 is 25% of 20, which is far greater than the 0.1 calculated from ½%.

D) 10

This option is also incorrect because 10 is 50% of 20. It overshoots the value of ½% significantly, which, as calculated, is only 0.1.

Conclusion

The correct answer is 1/10, as it accurately represents the calculation of ½% of 20. All other options fail to represent the outcome of the percentage calculation, either being too high or misrepresenting the fraction entirely. Thus, A is the only valid response.
