Which method would be used to express 1/2 in decimal form?

1. Multiply by two

2. Add the numerator to the denominator

3. Divide numerator by denominator

4. Combine with another fraction

The correct answer is: Divide numerator by denominator

To express 1/2 in decimal form, dividing the numerator by the denominator is the correct method. In this case, you would take the numerator, which is 1, and divide it by the denominator, which is 2. This calculation yields 0.5. This approach aligns with the fundamental concept of fractions, where the fraction represents a division operation. When you want to convert a fraction to a decimal, performing this division provides an accurate decimal representation of the fraction. The other methods do not achieve the intended result. Multiplying by two would double the fraction, resulting in 1 rather than converting it to a decimal. Adding the numerator to the denominator gives you 3, which does not represent the fraction accurately. Combining with another fraction does not apply to converting a single fraction to decimal form in this context and would complicate the operation unnecessarily.
