Abnormal decimal conversion help

I am auto-importing statistics from the web via web query. This information imported has a number in the form of a decimal stated as either x.1, or x.2. x.1 represents x-1/3 (one-third) and x.2 represents x-2/3 (two-thirds). I need to use these numbers in a calculation after importing them, but using x.1 or x.2 obviously does not give me accurate results as the numbers should actually be x.3333333 and x.6666666 respectively. What is the easiest way to convert the imported numbers to their actual decimals?...

You can use DOLLARDE perhaps ?

Where A1 holds x.1 ... B1: =DOLLARDE(A1,3) ... returns 1.333 etc...
