The question is poorly formatted, so I'll try to figure out what conversions you want.
If you have the fraction, just perform the division and look for the result:


If you have numbers, build a fraction as follows:
- the numerator is the number without decimal separator
- the denominator is 1 followed by as many zeroes as many decimal digits
0.9 is 9/10
0.4 is 4/10
1.4 is 14/10
