a) The number $2927.404$ to the nearest hundredth is $2927.40$. b) The number to the nearest ten is $2930$.
a) Since the last digit after the decimal is less than $5$, the previous digit of it will remain the same. Therefore, the number to the nearest hundredth will be $2927.40$. b) Since the tenth digit is less than $5$, we can remove the decimal part. Hence the number to the nearest ten is $2930$.
