Work Step by Step
72.789
We need to round-off the number to the nearest hundredth.
First cut off the number after hundredths place.
i.e. 72.78
look only the first digit you are cutting off. ignore other numbers.
i.e. look digit 9
If the first digit you are cutting off is 5 or more, round up the part of the number you are keeping.
Here it is 9 so round up by adding 1 hundredth to the part we are keeping.
i.e. 72.78 + 0.01 = 72.79.
So Answer is 72.79.
