The ROUND function will let you round your cells to the nearest decimal place of your choosing. Learn how to do so with two methods. You can use these techniques to round your numbers to the nearest decimal places required.
"=ROUND(Cell)"

The first technique is to use the function =ROUND(Cell).
This will round your numbers to the nearest ones place.
From there you can simply click and drag the function throughout all of your numbers

From there simply click and drag the function throughout the rest of your column.
"=ROUND(Cell, Tens-Place)"

If I wrote =ROUND (B6,2) that would round the number to the nearest hundredths place (10^-2). That would be 1325.34, which is 2 decimal points.
Tool Ribbon

one final honorable mention would be the round up/down tools in the top menu toolbar. the one on the left removes decimals, while the one to to right adds decimals.
It will have the same effect as those previous functions, and I personally prefer it, because it is way quicker and easier than the other two. Also, make sure that you highlight all of the cells that you want to round up or down.
And there you have it; that is how you round numbers in Google Sheets.
