In engineering, the precision of a quantity is implicitly told in the
number of digits presented. In the number 254.34, the precision
is of six digits.
If by one hundredth it is meant 1/100 of the unit then the number
in question is already given to the nearest hundredth. No more
rounding is necessary.
If the rounding is going to be down to the nearest hundred, then the number
is written as 3 x 10^2. This means the quantity has dropped down to a one order
magnitude level. Precision of the number is just of one digit.
RafaelRZ :The answer provided by' Ericbames' is correct.
It is already to the nearest hundredth as 9.69
30.45
47.12
18.84
4.35 is the answer rounded to the 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'
It is 1.54 rounded to the nearest hundredth
It is already to the nearest hundredth as 9.69
0.72 is already rounded to nearest hundredth. Remember column names. '0' ; units Decimal point '7' ; tenths '2' ; hundredths. NB The next digit to the right would be ' thousandths'.
