Decimals to Fractions
Each decimal fraction may be represented as a vulgar fraction. In the case of terminating decimal fractions you simply move the decimal point to the right and take the corresponding power of ten as its denominator.
As for recurring decimal fractions see formulas below:
_ _ _
0.1 = 1/9 , 0.2 = 2/9 , ... , 0.9 = 9/9 = 1
_ _
0.01 = 1/90 , 0.02 = 2/90 , ...
__ __ ___
0.01 = 1/99 , 0.02 = 2/99 , ... 0.000001 = 1/999000
The program transforms recurring as well as terminating decimal fractions into vulgar fractions after you have entered the non-recurring part of the decimal and the recurring decimal separately.
Example:
Non-periodical part : 1.20
Period : 045
___
1.20045 = 120/100 + 45/99900 = 533/444
