There are 2 triangles and 4 rectangles out of a total of ten shapes. So we can add 2 and 4 to get the number of triangles or rectangles to be 6.
The to find the fraction we do the part divided by the whole
6/10 is the answer, which can be simplified to 3/5 because both 6 and 10 are divisible by 2.
Hope this helps
