Understanding the Decimal 0.83 Repeating as a Fraction

The decimal 0.83 repeating is a common example of a recurring decimal that can be converted to a fraction. This decimal representation is obtained by the repeating pattern of 83 after the decimal point. In mathematical terms, 0.83 repeating is equal to 83/99.

What is a Recurring Decimal?

A recurring decimal is a decimal number that has a repeating pattern of digits after the decimal point. In the case of 0.83 repeating, the pattern of 83 repeats indefinitely. Recurring decimals can be represented as fractions, which is where the beauty of mathematics comes into play.

Why Convert 0.83 Repeating to a Fraction?

Converting recurring decimals to fractions has numerous applications in mathematics, science, and engineering. One of the main reasons to convert 0.83 repeating to a fraction is to simplify calculations and avoid dealing with recurring decimals. Fractions are also easier to work with in mathematical expressions and equations.

Converting 0.83 Repeating to a Fraction

To convert 0.83 repeating to a fraction, we can use the following steps:

• Let x = 0.83 repeating.
• Multiply both sides of the equation by 100 to eliminate the decimal point: 100x = 83.83 repeating.
• Subtract the original equation from the new equation to eliminate the recurring decimal: 100x - x = 83.83 repeating - 0.83 repeating.
• Combine like terms: 99x = 83.
• Solve for x: x = 83/99.

The Fraction 83/99

The fraction 83/99 can be further simplified by finding the greatest common divisor (GCD) of 83 and 99. In this case, the GCD is 1, which means that 83 and 99 are relatively prime. Therefore, the fraction 83/99 is already in its simplest form.

Real-World Applications of 0.83 Repeating as a Fraction
