Oct 13, 2025 by wbrum.org 67 views

Introduction

Darlene, a dedicated parent, baked 12 brownie pans for the school fair. She wanted to share her delicious treats with the students, particularly the 5th grade class. However, she decided to cut out a portion of each pan for the 5th grade class. In this problem, we will determine how many pans the 5th grade class will have after Darlene cuts out a quarter of each pan.

Understanding the Problem

To solve this problem, we need to understand the concept of fractions and how to apply it to real-world scenarios. A fraction represents a part of a whole, and in this case, Darlene is cutting out 1/4 of each pan. We will use this information to calculate the number of pans the 5th grade class will have.

Calculating the Number of Pans

Let's start by calculating the number of pans Darlene will cut out for the 5th grade class. Since she is cutting out 1/4 of each pan, we can multiply the total number of pans (12) by the fraction 1/4.

12 \times \frac{1}{4} = 3

This means that Darlene will cut out 3 pans for the 5th grade class. However, we need to determine how many pans the 5th grade class will have after Darlene cuts out these pans.

Applying the Concept of Fractions

To find the number of pans the 5th grade class will have, we need to subtract the number of pans Darlene cut out (3) from the total number of pans (12).

12 - 3 = 9

However, this is not the correct answer. We need to consider that Darlene cut out 1/4 of each pan, which means that the 5th grade class will receive 3/4 of each pan. To find the total number of pans the 5th grade class will have, we need to multiply the total number of pans (12) by the fraction 3/4.

12 \times \frac{3}{4} = 9

This means that the 5th grade class will have 9 pans.

Conclusion

In conclusion, Darlene baked 12 brownie pans for the school fair and cut out 1/4 of each pan for the 5th grade class. To find the number of pans the 5th grade class will have, we multiplied the total number of pans (12) by the fraction 3/4. The result is that the 5th grade class will have 9 pans.

Answer

The correct answer is D. 9.

Discussion

This problem requires an understanding of fractions and how to apply them to real-world scenarios. It also requires the ability to multiply fractions and subtract numbers. The problem is relevant to the topic of mathematics and can be used to teach students about fractions and their applications.

Real-World Applications
