Text Fraction to formula MK2

I have a spreadsheet with text based fraction values. I would like to convert these fractions into decimals in an adjacent column. I asked a similar question the other day, but I'm still having issues.
Basically, I am wondering if there is an easy way to convert 1/8 in B2 to =1/8 in B3.

The first rows of my text column looks like this.

2
1-1/4
1/8
9/32

where 1-1/4 represents 1+(1/4)

As you can see, there are a few different styles of values. Any ideas?
