Answer:
The length of blue-and-yellow macaw is 27 inches.
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:
![(2x)/(3) =18](https://img.qammunity.org/2019/formulas/mathematics/middle-school/s6qo9kcqa8tlhjcjbmcagx22js004289vf.png)
=>
![2x=54](https://img.qammunity.org/2019/formulas/mathematics/middle-school/wz7u5yu8lrietkvm2e4kx3t68l087cdsu0.png)
x = 27
Hence, the length of blue-and-yellow macaw is 27 inches.
