What number is 4 times as many as 25?
The Correct Answer and Explanation is :
To find the number that is 4 times as many as 25, we simply multiply 25 by 4.
[
25 \times 4 = 100
]
Thus, the number that is 4 times as many as 25 is 100.
Explanation
The concept of “times as many” refers to multiplication, which is a fundamental mathematical operation used to determine how many times a number can be added to itself. In this case, when we say we want a number that is 4 times as many as 25, we are effectively asking for the result of adding the number 25 to itself 4 times.
Let’s break it down step by step:
- Understanding Multiplication: Multiplication is a way of adding a number multiple times. For instance, saying “4 times 25” means we add 25 four times:
[
25 + 25 + 25 + 25
] - Calculating Step-by-Step:
- First addition: 25 + 25 = 50
- Second addition: 50 + 25 = 75
- Third addition: 75 + 25 = 100
- Using the Multiplication Equation: We can also use the multiplication equation to find the answer more efficiently. The operation can be set up as:
[
4 \times 25
]
This states that we are taking the number 25 and repeating it 4 times. - Result: When we perform the multiplication, we find that:
[
4 \times 25 = 100
]
In summary, 100 is the number that is 4 times as many as 25. This multiplication is not just a mere arithmetic operation but also reflects how quantities scale in various contexts, such as in finance, science, and everyday life, allowing for practical applications in calculating larger quantities based on smaller units. Understanding this basic principle of multiplication lays the groundwork for more complex mathematical concepts.
