To get the nearest whole number you first write the number of units you have. In this case, that number is 67. The next step is to look at the fraction and ask if it's greater than or equal to a half, in which case you round down. Otherwise, you round up. In this case, we have nine tenths, which is greater than a half, so you round 67 up to 68. Thus, the nearest whole number to 67 and 9/10 is 68.
