Changing 1/3 to a decimal:÷ 3 = 0.333… (The three repeats indefinitely).
The secret is recognizing the repeating sample. This sample may be explicitly famous utilizing a bar over the repeating digits (e.g., 0.3̄3̄).
Changing Recurring Decimals to Fractions
Reworking recurring decimals into fractions requires a particular method. Let’s illustrate this system:
Changing 0.6̄6̄ to a fraction:Let x = 0.6̄6̄ – x = 6.6̄6̄Subtracting the primary equation from the second:
- x – x = 6.6̄6̄
- 0.6̄6̄
- x = 6
x = 6/9 = 2/3
This technique permits us to precise recurring decimals of their fractional equivalents.
