If the last number is 5 or larger than 5, then you round up, but if it less than 5, than you round down.
\(Ex: 42.591\), round to nearest hundredth:
Because 1 is less than 5, then we keep the 9 there so the answer is \(42.59\)
\(Ex: 31.5727\), round the number to the nearest thousand:
Because 7 is greater than 5, then we round the 2 to 3 so the answer will be \(31.573\).
