Question

How do you round 8.762 to the nearest tenth?

Answer 1

See a solution process below:

Explanation:

First, we need to identify the tenth position.

The tenth position is the position to the right of the decimal point:

`8 .color(red)(7)62`

To round you look to the position to the right of the position you are trying to round to. In this case the `8` to the right of the `0` in the tenth place:

`8 .color(red)(7)color(blue)(6)2`

If the digit to the right is less than `5` you keep the digit you are rounding to the same and eliminate all the digits to the right.

If the digit to the right is greater than or equal to `5` you add 1 to the digit you are rounding to and eliminate all the digits to the right.

In this problem the digit to the right is `color(blue)(6)` which is greater than `5`. Therefore, we add `1` to the `color(red)(7)` and eliminate all the digits to the right:

`8 .color(red)(7)color(blue)(6)2` rounded to the nearest tenth is: `8 .color(red)(8)`
