When you take the total number of shapes (12) and the number of triangles (2) you have to divide them by one another - so (2/12) which simplifies to (1/6). Written as a ratio it should be 1 : 6 .
22 1/2 = 45/2 since 22*2+1 = 45, then divide that by 3/4 which, in reality, means multiply by 4/3. I then cross-multiplied by finding the GCF of the diagonal pairs. I hope this helped! Please mark Brainliest if it did.
