Hi Tanya, Try this in the command line:
r.mapcalc "newmap = 741.0 * 0.01" or in the GUI use the map calculator and put in your desired equation as above. The output of this command will be a new map with a value of 7.41. You can read about the mapcalc command here: http://grass.fbk.eu/gdp/html_grass64/r.mapcalc.html Hope that helps!
