Round 3.75 to the nearest whole number

The nearest hole number would be 4, if it is. 5 and above then it gets rounded up to the next number and if it is. 4 or less that you round it to the whole number

4

Because your round the last number out of 75 and the 5 makes the number change and move up. Anything that's bigger then 5 changes if it's below it stays and gets lower. 3.75 is like saying 3.80 but as a whole number you would use 4 that way you don't have a decimal in whatever your doing gets you confused.
