When rounding to the tenth, look at the next number (in your case, in the 100th column)... if it is 5 or greater, then add 1 to the tenth spot and drop the rest. If it's less than 5, then just drop the rest.
So, 7.93 rounded to the nearest tenth would be 7.9.
7.95, however, would be 8.0 (add 1 to the tenth)
