Which two methods can be used to convert between fractions and decimals?

Math, Subtraction
Math, Conversion
Division, Addition
Multiplication, Simplification

The correct answer is: Math, Conversion

The correct method to convert between fractions and decimals is through understanding basic mathematical conversions. In particular, division plays a key role: when converting a fraction to a decimal, you divide the numerator (the top number of the fraction) by the denominator (the bottom number). This operation yields a decimal result. Moreover, if one wants to convert a decimal back into a fraction, multiplying by an appropriate power of ten (depending on the number of decimal places) and then simplifying the resulting fraction can help achieve the desired conversion. This process reinforces the understanding of conversion between the two forms of representation. In this context, the concept of 'conversion' encompasses these mathematical operations rather than focusing solely on operations like subtraction or addition, which are not directly involved in converting between fractions and decimals. Hence, the answer focusing on 'Math, Conversion' correctly emphasizes the needed process.
