Unraveling the Problem Statement
The problem statement presents us with the following information:
- Pablo has 78 chickens.
- Pablo has twice as many hens as chickens.
The objective is to determine the total number of hens Pablo possesses. To solve this problem effectively, we need to translate the word problem into a mathematical equation. The phrase "twice as many" indicates a multiplicative relationship, where the number of hens is two times the number of chickens.
Transforming Words into Equations
Let's represent the number of hens with the variable 'h'. Based on the problem statement, we can express the relationship between the number of hens and chickens as follows:
h = 2 * (number of chickens)
Since we know that Pablo has 78 chickens, we can substitute this value into the equation:
h = 2 * 78
Calculating the Number of Hens
Now, we simply perform the multiplication to find the value of 'h':
h = 156
Therefore, Pablo has 156 hens.
The Importance of Careful Reading and Interpretation
This problem underscores the importance of careful reading and interpretation of word problems. Misinterpreting the phrase "twice as many" could lead to an incorrect equation and, consequently, an incorrect answer. By meticulously analyzing the problem statement and translating it into a mathematical equation, we can arrive at the correct solution.
Expanding the Problem: Additional Scenarios and Considerations
To further enhance our understanding of this problem-solving approach, let's explore some additional scenarios and considerations:
Scenario 1: Different Multiplicative Relationships
What if Pablo had three times as many hens as chickens? In this case, the equation would be:
h = 3 * (number of chickens)
Substituting the value of 78 chickens, we get:
h = 3 * 78 = 234
So, if Pablo had three times as many hens, he would have 234 hens.
Scenario 2: Introducing Additional Poultry
Let's add another layer of complexity. Suppose Pablo also has 50 ducks. Now, the question could be: what is the total number of poultry Pablo has? To solve this, we would add the number of chickens, hens, and ducks:
Total poultry = chickens + hens + ducks
Total poultry = 78 + 156 + 50 = 284
Therefore, Pablo would have a total of 284 poultry.
Scenario 3: Percentage-Based Relationships
Instead of "twice as many," the problem could state a percentage-based relationship. For example, Pablo has 50% more hens than chickens. In this case, we would first calculate 50% of the number of chickens:
50% of 78 = (50/100) * 78 = 39
Then, we would add this value to the number of chickens to find the number of hens:
Hens = 78 + 39 = 117
So, if Pablo had 50% more hens than chickens, he would have 117 hens.
