Answers and Step-by-step explanations:
When rounding, you should always look at the placement behind what you are trying to round to. So instead of looking at the hundred's placement, which is 0, we need to look at the ten's placement.
(Important:) When rounding, you should always remember that if a number is 1 - 4 when rounding, it does not round up the the next placement. If a number is 5 - 9, then it gets rounded to the next placement.
<em>Hundred's placement:</em> The 9 in the <u>ten's spot </u>(5,0<u>[9]</u>9.620) is on the 5 - 9 scale, so the hundred's placement rounds up to the next number.
5,100.620
<em>Hundredth's placement:</em> Anytime that the "th" is at the end of a word like "hundred" in rounding, it means to go behind (or to the right of) the decimal point. So, 2 falls into the 1 - 4 scale, so it doesn't get rounded.
5,099.600 (or 5,100.600 because of the answer earlier.)
I hope this helps.
