1. 23,758 rounded to the nearest ten, 5 is the target

23,760

Step-by-step explanation:

8 is on the 'Ones' place value

5 is on the 'Tens' place value

So, consider the number on the 'Ones' place value and check if it is greater or equal to 5, if so,  you round it up to 10, if not you round it down to 0.

8 > 5, So you round up 58 to 60 to get 23760.

Check that 58 is closer to 60 than 50.
