How can a fraction be converted into a decimal?

To convert a fraction into a decimal, the correct method is to divide the numerator by the denominator. This process turns the fraction, which represents a part of a whole, into a decimal form that is often easier to work with in calculations or comparisons.

For example, if you have the fraction 3/4, you would take the numerator (3) and divide it by the denominator (4). This division results in 0.75, which is the decimal representation of the original fraction. This method accurately reflects the value represented by the fraction and is a fundamental concept in mathematics that applies to various fields, including aviation mechanics, where precise calculations regarding parts and measurements are crucial.

The other options do not produce an accurate conversion from a fraction to a decimal, as they involve either multiplication, addition, or finding a least common multiple, none of which serve the purpose of changing a fraction into its decimal equivalent.
