6 Of What Number Is 270

6 of What Number is 270? Unlocking the Power of Algebra

This seemingly simple question, "6 of what number is 270?", opens the door to a fundamental concept in mathematics: algebra. While the answer might seem immediately obvious to some, understanding the underlying principles and exploring the various methods to solve this problem lays a solid foundation for tackling more complex algebraic equations. This article will delve into different approaches to finding the solution, discussing the concepts of variables, equations, and the power of algebraic manipulation. We'll even explore real-world applications of this type of problem.

Understanding the Problem: Translating Words into Math

The first step to solving any word problem is to translate the words into a mathematical equation. Let's break down the question, "6 of what number is 270?"

• "6 of": This indicates multiplication. We're taking 6 and multiplying it by something.
• "what number": This is our unknown, the value we need to find. In algebra, we represent unknowns with variables, usually letters like x, y, or z. Let's use x.
• "is 270": This signifies equality. The result of our multiplication equals 270.

Therefore, the word problem translates to the algebraic equation: 6x = 270

Solving the Equation: Multiple Approaches

Now that we have our equation, we can use several methods to solve for x.

Method 1: Division

The most straightforward method is to isolate x by dividing both sides of the equation by 6:

6x = 270

6x / 6 = 270 / 6

x = 45

Therefore, 6 of 45 is 270.

Method 2: Inverse Operations

This method emphasizes the concept of inverse operations. Multiplication and division are inverse operations; they "undo" each other. Since the equation involves multiplication by 6, we can use division to isolate x:

6x = 270

x = 270 ÷ 6

x = 45

Again, we find that x = 45.

Method 3: Using Fractions

We can also express the problem as a fraction:

6/x = 270

To solve for x, we can cross-multiply:

6 = 270x

Then, divide both sides by 270:

x = 6/270

x = 1/45

This method shows the relationship between the elements slightly differently, emphasizing the fractional representation of the problem.

Verification: Checking Your Answer

It's crucial to always check your answer to ensure its accuracy. We can do this by substituting the value of x (which we found to be 45) back into the original equation:

6x = 270

6 * 45 = 270

270 = 270

Since the equation holds true, our solution, x = 45, is correct.

Expanding the Concept: Beyond Simple Equations

The problem "6 of what number is 270?" is a simple linear equation, but the principles involved extend to much more complex algebraic problems. Understanding how to solve this basic equation lays a solid foundation for:

• Solving more complex equations: Equations involving multiple variables, exponents, and other mathematical operations can be approached using similar techniques, often requiring a series of steps to isolate the unknown variable.
• Solving real-world problems: Algebraic equations are used extensively in various fields, from physics and engineering to finance and economics, to model and solve real-world problems.
• Understanding functions and relationships: The equation 6x = 270 represents a simple function where the output (270) is a direct multiple of the input (x). Understanding these relationships is essential in many areas of mathematics and science.

Real-World Applications: Where This Matters

While seemingly simple, the principle of solving for an unknown value based on a known relationship is incredibly useful in a vast array of real-world scenarios. Consider these examples:

• Calculating unit cost: If 6 items cost $270, how much does one item cost? This is directly analogous to our problem.
• Determining proportions: If a recipe calls for 6 cups of flour to make a certain amount of bread, and you want to make a larger batch using 270 cups of flour, how many times larger is your recipe?
• Finding average speed: If a car travels a certain distance in 6 hours at an average speed, and the total distance traveled is 270 miles, what was the average speed?
• Scaling projects: In construction or manufacturing, scaling up or down a project often requires proportional calculations, directly applying the principles demonstrated in this problem.
• Financial calculations: Determining the interest rate, principal amount, or time period in financial calculations often involves similar algebraic equations.

Beyond the Numbers: The Importance of Problem Solving

The problem "6 of what number is 270?" is more than just an algebraic exercise. It's a gateway to developing crucial problem-solving skills. The process of translating a word problem into a mathematical equation, choosing an appropriate solution method, and verifying the answer is a powerful skill applicable far beyond the realm of mathematics. These skills are valuable in any field requiring logical thinking and analytical abilities.
