What is 16.107 rounded to nearest hundredth?
Remember the column names.
'1' ; Tens
'6' ; Units
Decimal point
'1' ; Tenths
'0' ; Hundredths
'7' ; thousandths.
We need to check and adjust as necessary the 'hundredths' column.
We inspect the 'thousandths' column ; next column to the right. It the next column to the right is '5' or greater, then we add '1' to the hundredths column , and ignore everything else to the right.
In this case, the thousandths column is '7' ( greater than 5), so we add '1' to the hundredths column 0 + 1 = 1
Hence
16.11 The Answer!!!! ignore everything to the right.
NB Be int decimals or integers, for the number to adjusted, inspect the next number to the right. If less than '5' the given number remains as read. If 5 or greater, then add ;1; to the given number.
In all cases ignore all other numbers to the right.
E.g.
16.10499999.... remains as 16.10
#But
16.10500001111.... is 16.11
You just ignore the '9' and '0'
How do you write 5000.00 iN WRITING?
If it is a dollar amount, you could write 'five thousand dollars', or 'exactly five thousand dollars'. Both imply that there are no cents involved.
You could write exactly five thousand, since the .00 implies nothing of significance at or beyond the hundredths place. Or you could write five thousand to the nearest hundredth if the .00 is important to your narrative. You could also write five thousand point zero zero, but this seems affected and pedantic to me. How you write it will depend on your audience and the need for detail.
