Step 1 ：Let's denote the age of the turtle as \(t\) and the age of the parrot as \(p\).

Step 2 ：From the problem, we know that the turtle is half as old as the parrot. So we can write this as an equation: \(t = \frac{p}{2}\).

Step 3 ：We also know that in 10 years, the turtle will be \(\frac{3}{4}\) as old as the parrot. We can write this as another equation: \(t + 10 = \frac{3}{4}(p + 10)\).

Step 4 ：Now we have a system of two equations, and we can solve it to find the values of \(t\) and \(p\).

Step 5 ：The solution to the system of equations is \(p = 10\) and \(t = 5\), which means the parrot is 10 years old and the turtle is 5 years old.

Step 6 ：Therefore, Ava's turtle is 5 years old.

Step 7 ：Final Answer: Ava's turtle is \(\boxed{5}\) years old.
