How was mauna loa formed
OK, the whole Hawaiian Island chain is volcanic, formed from volcanoes which rose in turn from the ocean floor, erupted, formed an island around, then became less and less active in turn as the whole island chain moves away to the NW at 2 - 4 in per year.
Mauna Loa is one of 5 volcanoes which have formed the main island Hawaii. It is still active, and is a wide flattish volcano 4169 metres above sea level (13 679 ft).
It probably started erupting under the sea about 700 000 yrs ago, and rose above the surface about 400 000 yrs ago. It is a young volcano in geological terms as the oldest rocks found on its surface are 200 000 yrs old.
There is heaps more info here, but take care as some teachers do not like you to quote Wikipedia as a reference.

How is finding 9.12-4.8 similar to finding $9.12-$4.80?
Numbers can exist in our minds and on paper and be manipulated in their own right, ie without units, or they can be assigned units of something when being so used, eg $, miles, people, dogs, days etc.
So with units assigned all arithmetical operations are usually possible just the same, unless it does not make any logical sense.
How do you round 5,403.264 to the nearest hundred
Assuming you do mean to the nearest hundred, answer the question 'is this number closer to 5400 or 5500?' It is closer to 5400 (The first digit to the left of the decimal point is 'ones', the second place is 'tens', the third place is 'hundreds', so you look at the third digit to the left to round to the nearest hundred)
If, in fact, you meant hundredth, answer the question 'is it closer to 5403.26 or 5403.27?' It is closer to 5403.26 (The first digit to the right of the decimal point is 'tenths', the second digit is 'hundredths', so you look at the second digit to the right to round to the nearest hundredth)
