Explain how you would use a number line to round 148 to the nearest ten.
On the number line with every 10 marked off, is 148 closer to 140 or 150?
The answer will be 150
To use a number line to round 148 to the nearest ten, follow these steps:
1. Draw a horizontal line and label the endpoints with the nearest tens values. In this case, label the left endpoint as 140 and the right endpoint as 150.
140---------------150
2. Plot the given number, 148, on the number line. Locate the point between 140 and 150 where 148 falls.
140-----148--------150
3. Determine which side of the number line the point is closer to. In this case, it is closer to 150.
4. Finally, identify the nearest ten by looking at the endpoint closest to the plotted point. In this case, the nearest ten is 150.
Therefore, when rounding 148 to the nearest ten using a number line, it becomes 150.
To use a number line to round a number to the nearest ten, you can follow these steps to round 148 to the nearest ten:
1. Draw a number line that includes ten markers evenly spaced apart.
- Start with a vertical line.
- Label the first marker as 140, representing the nearest multiple of ten below the number you want to round.
- Label the last marker as 150, representing the nearest multiple of ten above the number you want to round.
130 140 150 160 170 ...
2. Locate the number you want to round, which in this case is 148.
- Mark the number 148 on the number line, between 140 and 150.
130 140 [148] 150 160 170 ...
3. Determine which multiple of ten your number is closer to.
- In this case, 148 is closer to 150, as it is located more towards the right on the number line.
4. Once you have determined which multiple of ten your number is closer to, round it to that multiple.
- Round 148 to the nearest ten, which is 150.
Therefore, rounding 148 to the nearest ten using a number line would result in 150.
