Answer:
She made 640 free throw attempts.
Step-by-step explanation:
First, you use the information from the question to make the equation 128/x = 1/5.
Next, you cross multiply 128 by 100 and I got 12800.
And you continue to cross multiply 20 by x.
Now, the equation you should have is 20x = 12800
You divide 20 by 12800 and you get 640.
