Answer 10

9.99876 to one decimal place is 10.0, which is rounded from 9.9.  It is rounded up because you use the next number (in the hundreths place) to determine if the number in the tenths spot (the one decimal place) stays the same, or is rounded up.  Because the number in the hundreths spot (two spaces over, the 9) is above 5, the number in the tenths spot (one space over, also 9) is rounded up as well.  9.9 rounded up becomes 10.0.

63.5623 to two decimal places is 63.56.  Here, you look at the number in the thousandths place (three spaces over) to determine if the number in the hundreths place (two spaces over) is rounded up or down.  Because the number in the thousandths place is a 2, the 6 does not need to be rounded up, and stays as-is.
