Answer 2

Given,

The main number is = 2.645

To find,

The rounded off value of the main number to one decimal place.

Solution,

To round off any decimal number, we have to keep in mind that that if the next digit after the necessary decimal place is equal or more than 5, then we will eliminate that number and add 1 to it's previous number.

In the given number, we want the rounded off value to one decimal place, so we will put a door between 6 and 4.

= 2.6|45

(4<5)

Now, the digit 4 is knocking at the door which is less than 5. So,we will just eliminate the digits on the right side of the door without adding anything to the left side of the door.

Round off value

= 2.6

Hence, the rounded off number will be 2.6
