0.3 = 0.3/1 = 3/10 (simplest number)
None, because there is no such thing as a fractoin.
1. Count the number of digit after (to the right of) the decimal point. Call this value X. 2. Write the decimal number as a string, without the decimal point. This will be the numerator of your fraction (or fractoin, as you prefer). 3. The denominator is 1 followed by X 0s. 4. Simplify.
9/4
5/4
3/5.
0.75 = 3/4

0.3 = 3/10
6/10 or 60/100
2/10=1/5
It is: 11/25 in its lowest terms
7/25
