Mistake one is wrong because the forgot the thousand

Mistake two is wrong because they rounded to the nearest 10 not hundred

Mistake three is wrong because 5 mean round up but they round rounded down

The answer is 6,400 because 5 can be rounded up.

For mistake 1 He or She has forgotten about the thousands.

For mistake 2 He or She thought he was rounding to the nearest 10.

For mistake 3 He or She has forgotten about the rule if it is 4 or bellow you round down if 5 or above you round up.

the 5 and above only go up

it is mistake 3 because if you round up you will get mistake 3
