Which of the following represents 50% as a decimal?

To determine which representation is correct for 50% as a decimal, it is important to understand how to convert percentages to decimals. A percentage is a fraction out of 100, so to convert 50% to a decimal, you divide 50 by 100. This calculation results in 0.50.

When expressed as a decimal, 50% can also be written as 0.5. Both 0.50 and 0.5 are equivalent because the trailing zero does not change the value of the number. Therefore, both forms are representations of 50% in decimal form.

Thus, selecting both 0.50 and 0.5 as correct answers accurately reflects the understanding that decimals can have different representations while retaining the same value.
