- Determine the two consecutive multiples of 10 that bracket 421
- 421 is between 420 and 430
- 425 is the midpoint between 420 and 430
- As illustrated on the number line, 421 is less than the midpoint (425)
- Therefore, 421 rounded to the nearest ten = 420
421 rounded to the nearest ten with a number line
