Round 4.75 to nearest whole decimal?

4.75= 4.8 
1-4 round it down
5-9 round it up.
ex.
1.23 3 so you round it to 1.20
5.76
take the first number after the decimal and turn it into a 8= 5.8
Hoped i helped:)

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
