Introduction
Mathematical problem solving is an essential skill that involves applying mathematical concepts and techniques to solve real-world problems. In this article, we will explore a mathematical problem that involves algebraic thinking and problem-solving strategies. The problem is as follows:
Problem Statement
People of Sundargram planted trees in the village garden. Some of the trees were fruit trees. The number of non-fruit trees were three more than four times the number of fruit trees. If the number of non-fruit trees planted was 63, find the number of fruit trees planted.
Step 1: Understand the Problem
The problem states that the number of non-fruit trees is three more than four times the number of fruit trees. Let's denote the number of fruit trees as x. Then, the number of non-fruit trees is 4x + 3.
Step 2: Identify the Given Information
We are given that the number of non-fruit trees planted was 63. This can be represented as an equation:
4x + 3 = 63
Step 3: Solve the Equation
To solve the equation, we need to isolate the variable x. We can do this by subtracting 3 from both sides of the equation:
4x = 63 - 3 4x = 60
Next, we can divide both sides of the equation by 4:
x = 60/4 x = 15
Step 4: Interpret the Solution
The value of x represents the number of fruit trees planted. Therefore, the number of fruit trees planted is 15.
Conclusion
In this article, we solved a mathematical problem that involved algebraic thinking and problem-solving strategies. We used the given information to set up an equation and then solved the equation to find the number of fruit trees planted. This problem-solving approach can be applied to a wide range of mathematical problems and real-world scenarios.
Discussion
This problem can be used to discuss various mathematical concepts, such as:
- Algebraic thinking: The problem requires the use of algebraic thinking to set up and solve an equation.
- Problem-solving strategies: The problem requires the use of problem-solving strategies, such as identifying the given information, setting up an equation, and solving the equation.
- Real-world applications: The problem has real-world applications, such as calculating the number of fruit trees planted in a village garden.
Additional Examples
Here are some additional examples of mathematical problems that involve algebraic thinking and problem-solving strategies:
- Example 1: A bakery sells a total of 250 loaves of bread per day. The number of whole wheat loaves sold is 3 more than the number of white bread loaves sold. If the number of white bread loaves sold was 90, find the number of whole wheat loaves sold.
- Example 2: A company has 3 more employees than the number of employees it had last year. If the company had 120 employees last year, find the number of employees the company has this year.
Solutions
Here are the solutions to the additional examples:
- Example 1: Let's denote the number of white bread loaves sold as x. Then, the number of whole wheat loaves sold is x + 3. We are given that the number of white bread loaves sold was 90. This can be represented as an equation:
x + 3 = 90
Subtracting 3 from both sides of the equation, we get:
x = 87
Therefore, the number of whole wheat loaves sold is 90.
- Example 2: Let's denote the number of employees the company had last year as x. Then, the number of employees the company has this year is x + 3. We are given that the company had 120 employees last year. This can be represented as an equation:
x + 3 = 120
Subtracting 3 from both sides of the equation, we get:
x = 117
