<u><em>Answer:</em></u>
4.9
<u><em>Explanation:</em></u>
To round a number to he nearest one decimal place, we check the number in the second decimal place:
1- If this number is<u> less than 5</u>, we round down. This means that we remove the number in the second decimal place and keep the number in the first decimal place as it is
2- If this number is <u>equal to or greater than 5</u>, we round up. This means that we remove the number in the second decimal place and add 1 to the number in the first decimal place
<u>Now, the given number is 4.93</u>
The number in the second decimal place is 3, which is less than 5.
This means that we will round down.
This will give us 4.9
Hope this helps :)
