While searching for a hidden oasis, Emek and Luna discovered that a sandstorm had scattered the desert milestone signs. They found markers labeled 125, 140, 130, 150, and 135 lying in the sand. To help travelers find the correct path again, they compared the numbers and placed the milestones in increasing order along the trail. After checking that every marker was in the right position, they followed the restored route and happily reached the cool oasis.

Hint
Compare 135 and 140 by their values, not by how close they are to another number.
Emek says 140 should come before 135 because 140 is closer to 150. Is Emek correct?
Yes, because 140 is closer to 150.No, because 135 is less than 140.Yes, because 140 has a larger tens digit.No, because 140 is the smallest number.Correct! Since 135 is less than 140, it comes first in increasing order.
Not quite. Increasing order means arranging numbers from the smallest to the largest.
