MYP Maths, Rounding off

If the digit after the one being rounded off is less than 5 then we round down.
If the digit after the one being rounded off is 5 or more then we round up.

Therefore,
3406 to the nearest 10 is 3410
27.74 to one decimal place is 27.7 (has 7 in the first decimal place and 4 in the second decimal place. Since 4 is less than 5 we retain the 7 and delete all digits after it)
25.2017 to two decimal places is 25.20 (has 0 in the second decimal place and 1 in the third decimal place. Since 1 is less than 5 we retain the 0 and delete all digits after it)

Hope these help
