For art class, a teacher bought 20 pounds of paste. Each student is going to use 4/5 of the paste to make a pinata. How many students can make pinatas?Just put a number for your answer!

Explanation
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.

11.3y = -4.52

Explanation
In the given equation, 11.3y is equal to -4.52. To solve for y, we need to isolate it on one side of the equation. To do this, we divide both sides of the equation by 11.3. This gives us y = -4.52 / 11.3. Simplifying this expression, we get y = -0.4. Therefore, the correct answer is -0.4.
