how do i convert decimal fraction into common fraction
It depends upon how many digits follow the decimal point. For example
0.1 = 1/10
0.34 = 34/100 = 17/50
0.756 = 756/1000 = 189/250
Try to reduce each fraction to simplest terms, if there is a common factor in the numerator and denominator, as I have done for the last two.
