Indeed, because it is correct.

Perhaps #asApproximateFraction is what you are after.

Computers generally do what you tell them, not what you mean. 0.1  
does have a different meaning than 1/10 in computing land. If you  
mean a fraction, write a fraction. If you mean a float, write a  
dotted decimal. Smalltalk even has means to write fractions as  
decimals (0.1s1). So simply choose what you mean and write that in  
the language your computer understands.
