Hi there,
When you are rounding you must make sure that the number to your right is bigger than 5 or smaller than 5, if it’s bigger than 5 then the number you’re rounding will increase by one. If it’s smaller than 5 then it will decrease by zero.
In this case we are asking to round to the nearest tenth.
The 8 is the tenth so round 4
5 > 4
So the 4 would turn into a zero.
Your answer is 25.80.
