0.010 Repeating as a Fraction
In mathematics, a repeating decimal is a decimal that has a sequence of digits that repeats indefinitely. One such example is 0.010 repeating, which has a pattern of 0 and 1 repeating forever. But have you ever wondered what this repeating decimal represents as a fraction?
Defining Repeating Decimals
A repeating decimal is a decimal that has a sequence of digits that repeats indefinitely. For example, 0.12341234... is a repeating decimal where the sequence "1234" repeats forever. Repeating decimals can be classified into two types: purely periodic and eventually periodic.
Converting 0.010 Repeating to a Fraction
To convert 0.010 repeating to a fraction, we can use the following method:
Let x = 0.0101010...
Multiply both sides by 100 to get: 100x = 10.101010...
Subtract the original equation from the new equation to get: 99x = 10
Divide both sides by 99 to get: x = 10/99
So, 0.010 repeating is equal to 10/99.
Properties of 10/99
- 10/99 is a rational number, which means it can be expressed as a finite decimal or a ratio of integers.
- 10/99 is an infinite repeating decimal, which means it has an infinite number of digits that repeat indefinitely.
- 10/99 is an irrational number, which means it cannot be expressed as a finite decimal or a ratio of integers.
Real-World Applications of 0.010 Repeating
