This is a ratio question. You assigned wrong values. First start with assigning the values.

QS/QV=1/3, from the figure you see that QS is a part of QV. QS is 1, then SV is 2.
PT/PR=3/4, again you see that PT is a part of PR. PT is 3, then TR is 1(4-3).

Now find the areas of the triangles. The area of PST is 2x3/2=3. The area of PQR is 3x4/2=6.

The value of the fraction is 3/6.
