Alternatively, find lcm of numerator and make all numerators the same. In this case it should be 120. Compare the denominator. The one bigger than 240 is the answer.

Express 1/2 as an equivalent fraction to each option. (1) 1.5/3 (2) 3.5/7 (3) 4.5/9 (4) 5.5/11 Then from here you can see that option 2 is less than 1/2

Just by observation of all the denominators in the options. Only option 2 has a numerator that is less than half of the denominator.
