Answer: 16 asterisks
Explanation:
What I did was trying to get 1/6 of the 5/6, so I divided the 20 by the 5 and got 4, that means every 1/6 is every 4 asterisks. It's asking for 2/3, So I multiplied 1/6 by 4 since 2/3 is equivalent to 4/6, I got 4/6. Since 1/6 is for every 4 asterisks, 4 x 4 is 16.
