Introduction

Math problems can be a fun and challenging way to exercise our minds, but sometimes, even with the best intentions, we can make mistakes. In this article, we will explore a math problem presented by Marta to Maribel, and we will uncover the error made by Maribel in her solution.

The Problem

Marta told Maribel, "The sum of fifty and half the number of oranges is the same as one hundred twenty." Maribel wrote the equation $50\left(\frac{1}{2}\right) + m = 120$. But is this equation correct? Let's dive in and find out.

Understanding the Problem

To solve this problem, we need to understand what Marta is saying. She is telling Maribel that the sum of 50 and half the number of oranges is equal to 120. This means that we need to find the value of the number of oranges, denoted by the variable m.

Maribel's Equation

Maribel wrote the equation $50\left(\frac{1}{2}\right) + m = 120$. But is this equation correct? Let's analyze it step by step.

First, we need to evaluate the expression $50\left(\frac{1}{2}\right)$. This is equal to 25, since 50 multiplied by 1/2 is 25.

So, the equation becomes $25 + m = 120$. But this is not the correct equation. Let's think about what Marta said. She said that the sum of 50 and half the number of oranges is equal to 120. This means that we need to add 50 to half the number of oranges, not just add 25.

The Error

The error made by Maribel is that she wrote the equation $50\left(\frac{1}{2}\right) + m = 120$. This equation is incorrect because it does not represent the sum of 50 and half the number of oranges.

The correct equation should be $50 + \frac{1}{2}m = 120$. This equation represents the sum of 50 and half the number of oranges, which is equal to 120.

Conclusion

In conclusion, Maribel made a mistake in writing the equation $50\left(\frac{1}{2}\right) + m = 120$. The correct equation should be $50 + \frac{1}{2}m = 120$. This equation represents the sum of 50 and half the number of oranges, which is equal to 120.

What We Learned
