Question 17

0.64 as a percent is 64%

To convert the decimal 0.64 to a percent, you multiply by 100, resulting in 64%. This indicates that 0.64 is equivalent to 64 out of 100.

A) 0.64%

This option is incorrect because it implies that 0.64 is only a fraction of one percent. To convert a decimal to a percent, you must multiply by 100, not simply place a percent sign after the decimal.

B) 64%

This is the correct answer as it accurately reflects the conversion of the decimal 0.64 into a percent. By multiplying 0.64 by 100, we achieve 64%, which represents the value correctly.

C) 6.40%

This option is incorrect because it suggests that 0.64 is equivalent to 6.40%. This error arises from misunderstanding the conversion process; multiplying 0.64 by 100 gives 64%, not 6.40%.

D) 0.06%

This option is also incorrect because it underestimates the value of 0.64 significantly. Again, the correct conversion requires multiplying by 100, which clearly shows that 0.64 represents 64%, not a tiny fraction of a percent.

Conclusion

The correct conversion of the decimal 0.64 to a percent is 64%, making option B the definitive answer. All other options fail to accurately represent this conversion, either by reducing the value or misinterpreting the calculation process. Thus, understanding the multiplication by 100 is crucial for correct decimal-to-percent conversions.
