hello
to solve this problem, we need to know the total number of triangles in the diagram
i'lll go ahead and count it
we have 5 triangles plus the large triangle making it a total of 6 triangles
assuming all the triangles are of equal size,
we'll have a case of 1:6
that is, 1/6
the fraction of the large triangle represented in each region is 1/6
