The teacher bought 20 pounds of paste and each student is going to use 4/5 of the paste to make a pinata. To find out how many students can make pinatas, we need to divide the total amount of paste by the amount used per student. Therefore, 20 divided by 4/5 is equal to 25. Hence, 25 students can make pinatas.
