The decimal number 0.475 can be converted to a fraction in simplest form by following these steps:
- Divide the decimal number by 1 to remove the decimal point: 0.475 ÷ 1 = 475/1000
- Simplify the fraction by finding the greatest common divisor (GCD) of the numerator and denominator: GCD(475, 1000) = 25
- Divide both the numerator and denominator by the GCD to simplify the fraction: (475 ÷ 25) / (1000 ÷ 25) = 19/40
Therefore, the decimal number 0.475 can be expressed as the fraction 19/40 in simplest form.
Understanding Decimal to Fraction Conversion
Converting decimals to fractions is an essential math skill that can be used in various real-world applications, such as cooking, finance, and science. A decimal is a way of expressing a number using a point (.) to separate the whole part from the fractional part. A fraction, on the other hand, is a way of expressing a number as a ratio of two integers.
To convert a decimal to a fraction, you can use the following steps:
- Divide the decimal number by 1 to remove the decimal point.
- Simplify the fraction by finding the greatest common divisor (GCD) of the numerator and denominator.
- Divide both the numerator and denominator by the GCD to simplify the fraction.
Real-World Applications of Decimal to Fraction Conversion
Decimal to fraction conversion has numerous real-world applications, including:
- Cooking: Recipes often require precise measurements, which can be expressed as fractions. For example, a recipe may call for 3/4 cup of flour or 1/2 teaspoon of salt.
- Finance: Financial calculations, such as interest rates and investment returns, often involve decimal to fraction conversion. For example, an interest rate of 0.05 can be expressed as a fraction of 5/100.
- Science: Scientific measurements, such as temperature and time, often require decimal to fraction conversion. For example, a temperature of 0.5°C can be expressed as a fraction of 1/2°C.
