It's 0.28 because 7 is greater than 4 so you round the number before that up by 1
The answer is 0.28 cause in .277 the first seven is in the hundredths place so if you look at the number after, in this case a 7, if its above 5 you round the number to the left of it up but if its under 5 it stays the same
