How to treat data pasted into Google Sheets as number instead of text and sort accordingly?

I pasted a table into Google Sheets (part of Google Docs), and one column is

1/234
1/102
1/1222
1/83

and when sorted according to this column, the column data is treated as "text" and sorted accordingly, meaning 1/102 and 1/1222 both go to the front of the table. Is it possible to sort them as numbers?
