manually rounded off to the nearest hundredths

rounded off by the computer to the nearest whole number

9.27830
0.53544
58.0055
7,888.51945

Step-by-step explanation:

Consider the provided numbers.

9.27830

0.53544

58.0055

7,888.51945

We need to Round the numbers.

To round off nearest whole number we need to look at the first digit after the decimal point. If the digit is 1, 2, 3, 4 then we don't have to do anything, if the digit is 5, 6, 7, 8, 9 we must round up.

To round off the number to the nearest tenths we need to look at the hundredths place digit. If the digit is 1, 2, 3, 4 then we don't have to do anything, if the digit is 5, 6, 7, 8, 9 we must round up.

To round off the number to the nearest hundredths we need to look at the thousandth place digit. If the digit is 1, 2, 3, 4 then we don't have to do anything, if the digit is 5, 6, 7, 8, 9 we must round up.

Now use the above mentioned rule and round off the numbers as shown:

9.278310 first round the number to nearest whole number.

Whole number round off: The number after decimal point is 2 so the whole number round off of 9.278310 is 9.

Nearest tenths: The number at hundredths place is 7 so round up the tenths place digit, hence the rounded off to the nearest tenths is 9.3

Nearest hundredths: The number at thousandth place is 8 so round up the hundredths place digit, hence the rounded off to the nearest hundredths is 9.28

Round of by computer to nearest whole number is 9.

Consider the number 0.53544

Whole number round off: The number after decimal point is 5 so round up the ones digit, hence the rounded off to the nearest whole number is 1.

Nearest tenths: The number at hundredths place is 3 so the rounded off to the nearest tenths is 0.5

Nearest hundredths: The number at thousandth place is 5 so round up the hundredths place digit hence the rounded off to the nearest hundredths is 0.54

Round of by computer to nearest whole number is 1.

Similarly,

Consider the number 58.0055

Whole number round off is 58.

Nearest tenths round off is 58.0

Nearest hundredths round off is 58.01

Round of by computer to nearest whole number is 58.

Consider the number 7,888.51945

Whole number round off is 7889.

Nearest tenths round off is 7888.5

Nearest hundredths round off is 7888.52

Round of by computer to nearest whole number is 7889.
