Introduction

Darlene, a dedicated baker, has prepared 12 brownie pans for the school fair. However, she has decided to cut out a portion of each pan for the 5th grade class. In this scenario, we need to determine how many pans the 5th grade class will receive. To do this, we must calculate the fraction of the pans that Darlene will cut out for the 5th grade class.

Calculating the Fraction of Pans

Darlene will cut out $\frac{1}{4}$ of each pan for the 5th grade class. To find the number of pans the 5th grade class will receive, we need to multiply the total number of pans by the fraction that will be cut out.

Mathematical Representation

Let's represent the total number of pans as $T$ and the fraction of pans that will be cut out as $f$ . In this case, $T = 12$ and $f = \frac{1}{4}$ .

The number of pans the 5th grade class will receive can be calculated as follows:

\text{Number of pans} = T \times f

Substituting the values of $T$ and $f$ , we get:

\text{Number of pans} = 12 \times \frac{1}{4}

Simplifying the Expression

To simplify the expression, we can multiply the numerator and denominator by 4:

\text{Number of pans} = \frac{12 \times 4}{4 \times 4}

\text{Number of pans} = \frac{48}{16}

Final Calculation

Now, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 16:

\text{Number of pans} = \frac{48 \div 16}{16 \div 16}

\text{Number of pans} = \frac{3}{1}

Conclusion

Therefore, the 5th grade class will receive $\boxed{3}$ pans.

Answer Key

The correct answer is A. 3.

Conclusion

In this article, we addressed some frequently asked questions related to the scenario of Darlene preparing 12 brownie pans for the school fair and cutting out a portion of each pan for the 5th grade class. We calculated that the 5th grade class will receive $\boxed{3}$ pans and used the concept of fractions to simplify the expression.

Additional Information

In this problem, we used the concept of fractions to calculate the number of pans the 5th grade class will receive. Fractions are used to represent a part of a whole, and in this case, the fraction $\frac{1}{4}$ represents the portion of each pan that will be cut out for the 5th grade class. By multiplying the total number of pans by the fraction that will be cut out, we can determine the number of pans the 5th grade class will receive.

Practice Problems

If Darlene cuts out $\frac{1}{3}$ of each pan for the 6th grade class, how many pans will the 6th grade class receive?
