Hello, KKLU:  Mind showing us how you got 6.30?

anonymous · Answer

i did the same as you but i put a different number from where you put 6.28

anonymous · Answer

you divide 12.56 by 2 and get 6.28 and dont round up

anonymous · Answer

ok so rounding down correct? i rounded down and i got 6.

thats how i got 6

mathmale · Answer

The numbers you are given are written to 2 decimal places, so write your answer with 2 decimal places also.  No reason to round up or down, at least not in this problem.
