What does it mean to round to the nearest tenth?
Rounding off a number is done that makes them simpler and easier to use.
Answer: Rounding off a number to the nearest tenth means that you have to look or find the tenth which is closest to the given number and then write that as the rounded-off number.
Let's look at this number line to understand this:
Case 1: To round off 0.14
The nearest tenth to 0.14 is 0.1. Therefore 0.14 can be rounded off to 0.1.
Case 2: To round off 0.15
The number 0.15 is exactly in the middle of 0.1 and 0.2, but we will always take the higher tenth in such a case. Therefore 0.15 can be rounded off to 0.2
So, to round off a number to the nearest tenth, we check the digit at the hundredth place. If it is less than 4, then we remove all the digits to the right of the tenth digit. If the digit at the hundredth place is more than 5, we add 1 to the digit at the tenth place.
