Elena bought 6.39 pounds of apples. What is 6.39 rounded to the nearest whole number?

The nearest whole number is the number immediately before the decimal, the number 6

Then to determine weather the number goes up or stays the same, look at the number before it which in this case is 3

3 is less than 5 so the number doesn't round up, it stays at 6

6.39 rounded to the nearest whole number is 6

6 because 6.39 isn't half way if it was 6.50 it would've been 7 so the answer is 6.00
