Answer 5

The easiest way to do the harder types of these questions is to follow a simple plan (I'll say this only once.....)

To 2 dp we have 9.99 (our primary number) so draw a line here to separate this from the remaining numbers 876.  If the remaining numbers begin with a 5 or more then you add a 1 to the end of the primary number. The remaining numbers begin with 8 so we add a 1 to the end of our primary numer i.e. 9.99 + 0.01 = 10.00.

Don't forget that the answer is still going to be close to the original answer and if it asks for 2 decimal places then there will be 2 deimal places, even if they are zero.  

Answer 6

10.00 i think =]

Hope I've helped =]

Answer 7

You always look at the next number over to figure out whether you should round up or leave a number as-is.  Since you're simplifying to two decimal places, begin with the third decimal place over - 8.  It is higher than 5, so the second decimal place rounds up.  Because it is already a 9, the next-highest number up is 10 (signified by a 0 in that place).  Ten (signified by the 0 in the second decimal place over, or the hundreths spot), is also higher than 5, so the first number (in the tenths spot) is also rounded up.  Again, since the number was originally a 9, it must be rounded up to a 10 (or 0).  You continue moving over one space to the left, and because the number in the first decimal place (the tenths) was just rounded up to a 10 (signified by the 0), the whole number (on the left side of the decimal point) is also rounded up to 10.  

Your answer becomes 10.00.

Answer 8

10
