 Need to convert a repeating decimal to a fraction? Follow these examples:Note the following pattern for repeating decimals:0.22222222... = 2/90.54545454... = 54/990.298298298... = 298/999Division by 9's causes the repeating pattern. Note the pattern if zeros preceed the repeating decimal:0.022222222... = 2/900.00054545454... = 54/990000.00298298298... = 298/99900Adding zero's to the denominator adds zero's before the repeating decimal. To convert a decimal that begins with a non-repeating part, such as 0.21456456456456456..., to a fraction, write it as the sum of the non-repeating part and the repeating part.  0.21 + 0.00456456456456456...Next, convert each of these decimals to fractions. The first decimal has a divisor of power ten. The second decimal (which repeats) is convirted according to the pattern given above.  21/100 + 456/99900Now add these fraction by expressing both with a common divisor  20979/99900 + 456/99900and add.  21435/99900Finally simplify it to lowest terms  1429/6660and check on your calculator or with long division.= 0.2145645645...
