Question

How do you round 0.238 to the nearest tenth?

Answer 1

Hint: Rounding means making a number simpler but keeping its value close to what it was. The result is less accurate, but easier to use. The most common method to round is as follows:
Step 1. Choose which is the last digit to keep.
Step 2. Leave it the same if the next digit is less than \[5\].
Step 3. Increase it by \[1\] if the next digit is \[5\] or more.

Complete step by step answer:
We are asked to round 0.238 to the nearest tenth place, which means that round the number till all digits except tenth place are zero. We will do this by rounding the digits one after another.
The last digit to keep in 0.238 is 3, as the digit next to it is 8 which is larger than \[5\], thus it can be removed by adding 1 to its previous number. So, after rounding once 0.238 can be written as 0.24. To reach the nearest tenth place, we have to round it once more. Now, the last digit to keep is 2, as the digit next it is 4. 4 is smaller than \[5\], thus it can be left unchanged. So, after rounding 0.24 can be written as 0.2.

Hence, by rounding to the nearest tenth place 0.238 can be written as 0.2.

Note: like the decimal numbers, integers can also be round. The integers can also be rounded similarly. For example, 165 rounded to the nearest ten is 16, it can be done by following the same set of rules.
