Answer:
The blue and yellow macaw is 33 inches long. 
Explanation:
If the toucan is 22 inches long and it's two thirds the length of the macaw you can divide by two to find what one third is. 
22 ÷ 2 = 11
So then you have to multiply by 3 to find what the full length is. 
3 x 11 = 33 inches
Hope that helps and have a great day!
