Question: 1 / 400

Which of the following describes how to convert a decimal to a fraction?

Multiply by ten

Identify the place value and express accordingly

To convert a decimal to a fraction, identifying the place value and expressing it accordingly is the correct approach. When you have a decimal, the placement of the digits informs you about their respective value. For instance, in the decimal 0.75, the '7' is in the tenths place and the '5' is in the hundredths place. Thus, this decimal can be expressed as 75/100. You can then simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, leading to 3/4.

This understanding of place values is essential for accurately representing decimals as fractions without losing precision. Simply multiplying by ten or manipulating the whole number doesn't provide a complete or accurate method for conversion. Knowing how to identify place values ensures that the fraction is correctly formulated and reflects the decimal's true value.
