Answer:
The length of blue-and-yellow macaw is 27 inches.
Step-by-step explanation:
The length of the toucan is about two thirds of the length of the blue-and-yellow macaw.
The toucan is about 18 in long.
Let the length of blue-and-yellow macaw be x.
We know that 2/3 of x is equal to 18.
We get this as:
[tex]\frac{2x}{3} =18[/tex]
=> [tex]2x=54[/tex]
x = 27
Hence, the length of blue-and-yellow macaw is 27 inches.
