To determine whether 2/5 is greater or less than 1/2, we can compare the two fractions by converting them to have the same denominator.
First, find a common denominator for 2/5 and 1/2. The least common denominator (LCD) of 5 and 2 is 10.
Convert 2/5 to a fraction with a denominator of 10:
2/5 = (2 × 2)/(5 × 2) = 4/10
Convert 1/2 to a fraction with a denominator of 10:
1/2 = (1 × 5)/(2 × 5) = 5/10
Now, compare the two fractions:
4/10 < 5/10
Therefore, 2/5 is less than 1/2.
