Question 37

64%

To convert the decimal 0.64 into a percent, you multiply it by 100. This results in 64%, which is the correct conversion of the given decimal.

A) 0.64%

This option is incorrect because it suggests that the decimal is equal to 0.64 percent. To convert a decimal to a percent, you must multiply by 100, which means 0.64 is much greater than 0.64%.

B) 64%

This option is correct as it accurately represents the conversion of 0.64 into a percent. By multiplying 0.64 by 100, we obtain 64%, confirming that this is the proper transformation of the decimal.

C) 6.40%

This option is incorrect because it represents 0.064 in decimal form, not 0.64. The conversion process shows that 0.64 translates to 64%, not 6.40%.

D) 0.06%

This option is also incorrect as it suggests a much smaller value than what is represented by 0.64. In reality, 0.64 converted to a percent is 64%, not a fraction of that amount.

Conclusion

64% is the accurate conversion of the decimal 0.64, as it reflects the value after multiplying by 100. All other options misrepresent the conversion, either by indicating a significantly smaller percentage or by failing to apply the correct multiplication process. Thus, option B stands out as the only correct answer.
