What is 251 to the nearest 10?

251 rounded to the nearest ten with a number line

Determine the two consecutive multiples of 10 that bracket 251.
251 is between 250 and 260.
255 is the midpoint between 250 and 260.
As illustrated on the number line, 251 is less than the midpoint (255)
Therefore, 251 rounded to the nearest ten = 250.
