Change 0.50 to a Fraction

• Correct Answer: 1/2

Explanation :

To convert a decimal like 0.50 into a fraction, we follow a systematic approach. First, recognize that the decimal 0.50 is read as “fifty hundredths,” which can be written as the fraction 50100\frac{50}{100}.

Next, simplify the fraction by finding the greatest common divisor (GCD) of the numerator (50) and the denominator (100). The GCD of 50 and 100 is 50. Divide both the numerator and denominator by their GCD: 50÷50100÷50=12\frac{50 \div 50}{100 \div 50} = \frac{1}{2}

Thus, 0.500.50 simplifies to the fraction 12\frac{1}{2}.

This fraction represents the same proportion as the decimal, where half of a whole is equal to 0.50. Converting decimals to fractions is crucial in various contexts, especially in mathematics, cooking, and measurements. Fractions provide an alternative and often clearer way to represent parts of a whole, especially when exact division is involved.

Additionally, understanding the relationship between decimals and fractions enhances numerical literacy, enabling better comprehension of percentages and ratios. For example, 0.500.50, 12\frac{1}{2}, and 50% are all equivalent, showing the same proportion of a whole in different formats. This equivalence is valuable in everyday applications such as dividing resources, interpreting statistical data, or solving problems requiring precise calculations.
