In the realm of mathematics, the concept of multiplication holds a fundamental place. Multiplication, represented by the symbol ‘×’, signifies the repeated addition of a specific number. For instance, 3 × 4 represents the sum of four 3s, which equals 12.
When faced with the question, “3 times what equals 100?”, we embark on a mathematical quest to uncover the unknown factor that, when multiplied by 3, yields the desired result of 100.
Delving into the Mathematical Equation
To solve for the unknown factor, we can set up a simple mathematical equation:
3 × x = 100
where ‘x’ represents the unknown factor we seek to determine.
Solving this equation involves isolating ‘x’ on one side of the equation. To achieve this, we divide both sides by 3:
(3 × x) / 3 = 100 / 3
Simplifying the equation, we obtain:
x = 100 / 3
Evaluating the right-hand side of the equation, we find:
x = 33.333...
Therefore, the unknown factor that, when multiplied by 3, equals 100 is 33.333….
Applications of the Concept
The understanding of multiplication and the concept of “3 times what equals 100” finds applications in various real-world scenarios, including:
- Calculating quantities: In a manufacturing setting, a supervisor may need to determine the total number of parts required for an assembly. If each assembly requires 3 screws, and there are 100 assemblies to be made, the supervisor can use the concept of multiplication to calculate the total number of screws needed: 3 × 100 = 300 screws.
- Determining proportions: In a culinary context, a baker may need to adjust the recipe for a cake based on the desired number of servings. If the original recipe yields 12 servings and the baker wants to make a cake that serves 100 people, the baker can use multiplication to determine the proportions of each ingredient: 3 × 12 = 36 (the proportions are tripled).
- Estimating costs: In a business scenario, an entrepreneur may need to estimate the total cost of producing a batch of products. If each product costs $3 to produce, and the entrepreneur plans to produce 100 products, multiplication can be used to estimate the total cost: 3 × 100 = $300.
Tips and Tricks
- Remember the order of operations: When dealing with complex mathematical expressions, it’s essential to remember the order of operations (PEMDAS: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction). This ensures that the calculations are performed in the correct order.
- Use mental math: For simple multiplication problems like 3 times what equals 100, mental math can be a quick and efficient way to find the answer.
- Seek help when needed: If you struggle with multiplication or other mathematical concepts, don’t hesitate to reach out for help from a teacher, tutor, or online resources.
Common Mistakes to Avoid
- Misinterpreting the question: Ensure you understand what the question is asking before attempting to solve it. Make sure you grasp the concept of “3 times what equals 100” before proceeding.
- Using the wrong operation: Avoid using addition or subtraction instead of multiplication. Remember, multiplication is represented by the ‘×’ symbol and signifies repeated addition.
- Dividing instead of multiplying: Pay attention to the direction of the question. “3 times what equals 100” implies multiplication, not division.
