Since the shaded portion of triangle X is 1/3 that of the whole triangle X, this means we can take triangle X as 3 units.

We also know that triangle X is 1/4 that of triangle Y. Therefore, triangle Y will be (3 × 4 = 12) units.

The whole figure is then 12 + 3 – 1 = 14 units. We minus 1 unit because the shaded portion is an overlap between the two triangles and should not be counted twice.

So ratio of shaded portion to whole figure is 1 : 14 or **1/14 as a fraction**.
