Curious way of writing it.
The thing you're missing (and soooo many students do this) is the mismatch between the units for DH and DS. DH is in kJ mol-1, whereas DS is J K-1 mol-1.
You have to convert them to the same version of J. One way to do this, is to multiply the DH by 1000 (which is the same as 10*10*10).
