Answer:
1
Step-by-step explanation:
1.0079
The place value we must round to in order to get a whole number for this number is the one's place value, which the number 1 is occupying.
Now, we look at the previous place value to determine whether we round up or not. If it is 5 or greater, we round up and if not, the number stays the same. Because the previous place value is a 0 and 0 is less than 5, the 1 just stays the same.
