Answer: Nothin

--------------------------

I do not agree

If it were 76.245, yes 76.25

BUT it is not.

It is 76.24 + .00491

AND

.00491 is LESS THAN .00500

It is only if the next number is five or more that you round up.

So I say, 76.24

Answer: 280.100 (I do not get the 286 anyway)

not precise to more than tenths because 27.4 is NOT 27.400

so I say

280.1

period
