To round a number to the nearest 10 using a number line, follow these steps:
1. Draw a number line with the starting point being the closest multiple of 10 below the given number. In this case, the closest multiple of 10 below 148 is 140.
Number Line: ...130, 140, 150, 160...
2. Place the given number (148) on the number line.
Number Line: ...130, 140, 148, 150, 160...
3. Look at the numbers on either side of the given number. In this case, these are 140 and 150.
4. Determine which multiple of 10 is closest to the given number. In this case, 140 is closer to 148 than 150.
5. Finally, round the given number to the multiple of 10 that is closest. In this case, rounding 148 to the nearest 10 results in 140.
So, by using a number line, we can determine that 148 rounded to the nearest 10 is 140.
