What is 0.5 in fraction form?

The value of 0.5 can be expressed as a fraction by recognizing that it represents half of a whole. This can be directly translated to the fraction 1/2, as both depict the same quantity. To validate, when 1 is divided by 2, you indeed receive 0.5. This illustrates that 0.5 accurately corresponds to the fraction 1/2.

The other options do not equate to 0.5: 2/3, for example, is approximately 0.666, which is greater than 0.5; 3/4 equals 0.75, also above 0.5; and 4/5 translates to 0.8, further exceeding 0.5. Therefore, 1/2 stands out as the correct representation of 0.5 in fraction form.
