Answer:
80%
Explanation:
Think of the fraction and turn it into 20’s. This is because 20 x 5 = 100
This would mean that it would take 5 20’s to make 100.
Now, multiply 4 x 20 because this is how much you have in the fraction.
4 x 20 = 80.
Then, add the other 20, it would amount to 100.
I really hope this helped.
