Assuming your data is saved in file.txt:

awk '{printf "%s %s %.2f %.2f\n", $1, $2, $3, $4}' file.txt

This assumes that strings are present in columns 1-2 and prints them unchanged, and reduces numbers in columns 3-4 to two decimals.

If you want the resulting columns to be tab-separated:

awk '{printf "%s\t%s\t%.2f\t%.2f\n", $1, $2, $3, $4}' file.txt
