Question

Which of the following is the greatest when rounded off to the nearest tenths?

• A. 6.68
• B. 6.21
• C. 6.49
• D. 6.78

Answer 1

The correct option is D 6.78

To round off the digit in the tenths place, we look at digits in the hundredths place.

If the digit is less than 5, we keep the digit in the tenths place as the same and remove all the digits to its right.

But, if the digit in the hundredths place is 5 or more than 5, we increase the digit in the tenths place by 1 and remove all the digits to its right.


Comparing the estimates, we can find that 6.8 is the greatest.

So, out of the given numbers, 6.78 is the greatest when rounded off to its nearest tenths.
