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'
