Question
Round off the decimal 123.4896 to its nearest tenth.
- 123.5
- 123.4
- 123
- 124
Hint:
We have to round off the decimal 123.4896 to the nearest tenth. For the decimal number the first digit in the right side of the decimal point is tenth place, the second is hundredth and so on. So, for this question considering tenth place we can see that there is number 8 after 4. So, the 4 will be converted to 5, if there was number from 0 to 4 then 4 would have remained as 4.
The correct answer is: 123.5
Decimal 123.4896 to nearest tenth =123.5
