Two-fifths of the students walked to school. What fraction of the students did not walk to school?
To determine the fraction of students who did not walk to school, we need to subtract the fraction of students who did walk from 1 (since 1 represents the whole or the total number of students).
Given that two-fifths (2/5) of the students walked to school, we can calculate the fraction of students who did not walk by subtracting 2/5 from 1:
1 - 2/5 = 5/5 - 2/5 = 3/5
Therefore, the fraction of students who did not walk to school is 3/5.
