Rounding numbers

Question

My teacher wants me to round this number to the fourth decimal place.

57.2899616308

Answer 1

57.28996

5th decimal place is 6. 6 >4 so round 4th decimal place up to 0, carry 1 to 3rd decimal place

3rd decimal place is 9 + 1 = 10

carry 1 to 2nd decimal place. 8+1 = 9

So 57.2900 to 4 decimal places
