12. Describe A Situation That The Equation Could Represent: $\frac{9+3}{6}=15$13. Reasoning: Would The Situation You Wrote For Problem 12 Work If The Denominator In The Equation Were Doubled? Explain Why Or Why Not.

The equation $\frac{9+3}{6}=15$ may seem straightforward, but it can be used to represent a real-world situation. In this article, we will explore a scenario that this equation can represent and discuss the implications of changing the denominator.

A Real-World Scenario

Imagine a group of friends who want to share some candy equally among themselves. They have a total of 12 pieces of candy, and they want to divide it into 6 equal groups. Each group should receive the same amount of candy. To find out how many pieces of candy each group should get, we can use the equation $\frac{9+3}{6}=15$.

In this scenario, the numerator (9+3) represents the total number of pieces of candy, which is 12. The denominator (6) represents the number of groups the candy is being divided into. The equation tells us that each group should receive 15 pieces of candy. However, this is not possible, as there are only 12 pieces of candy in total.

The Problem with the Equation

The equation $\frac{9+3}{6}=15$ is incorrect, as it implies that each group should receive 15 pieces of candy, which is not possible with only 12 pieces of candy. This highlights the importance of ensuring that the numerator and denominator are consistent with the real-world scenario being represented.

Doubling the Denominator

Now, let's consider what would happen if the denominator in the equation were doubled. The new equation would be $\frac{9+3}{12}=15$. In the real-world scenario, doubling the denominator would mean that the group of friends is now dividing the candy into 12 equal groups, rather than 6.

Would the Situation Work?

In this case, the situation would not work if the denominator were doubled. The numerator (9+3) still represents the total number of pieces of candy, which is 12. However, the denominator (12) now represents the number of groups the candy is being divided into. The equation tells us that each group should receive 15 pieces of candy, which is still not possible, as there are only 12 pieces of candy in total.

Why It Doesn't Work

The reason why the situation doesn't work is that the numerator and denominator are not consistent with the real-world scenario. The numerator still represents the total number of pieces of candy, but the denominator has been doubled, which means that the group of friends is now dividing the candy into more groups than before.

Conclusion

In conclusion, the equation $\frac{9+3}{6}=15$ can represent a real-world scenario where a group of friends want to share candy equally among themselves. However, the equation is incorrect, as it implies that each group should receive 15 pieces of candy, which is not possible with only 12 pieces of candy. Doubling the denominator would not make the situation work, as the numerator and denominator would still be inconsistent with the real-world scenario.
