How would you use a number line to round 148 to the nearest ten.Explain.

When rounded to the nearest 10, the last digit is always 0. A number line will clearly show you which multiple of 10 is closest to 148.

To use a number line to round 148 to the nearest ten, follow these steps:

1. Draw a number line with the value of the 148 in the center. Mark the nearest tens on the left and right sides. For example, mark 140 and 150.

------140---------148---------150------

2. Determine which of the two nearest tens the number 148 is closer to. In this case, 148 is closer to 150.

3. Round the number up to the nearest ten if it is closer to the right mark, or down if it is closer to the left mark. Since 148 is closer to 150, round it up to 150.

Therefore, by using a number line, 148 would be rounded to the nearest ten as 150.
