When we round, we always round to a certain decimal place.“If the digit is less than 5, round the previous digit down; if it’s 5 or greater, round the previous digit up.” To round a digit down means to leave it unchanged; to round a digit up means to increase it by one unit.

Is the number 5 rounded up or down?
If you have 0.9, 9 is above 5 so you’d round to 1. If you have 0.1, the digit you are rounding is less than 5, so you would round down to 0. If it is 5, then you would round up. It is safe to do this one wherever something just says “round”.
Why do you round up when it is a 5?
The rule when it comes to rounding is : If the number to the place directly to the right of the number you want to round is a 5 or higher, then you round up. Otherwise, you found down.

How do you round 6?
If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you’re rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.
