Problem Description:
The image shows examples of decomposing numbers. Decomposing a number means breaking it down into smaller parts that add up to the original number. The task is to understand and explain how these numbers are being decomposed.
Solution Explanation:
#### What is Decomposing Numbers?
Decomposing numbers is a fundamental concept in mathematics where a number is broken down into its component parts. This helps in understanding the structure of numbers and simplifies arithmetic operations like addition, subtraction, multiplication, and division.
#### Examples from the Image:
The image provides several examples of decomposing numbers. Let's analyze each one step by step:
1.
Top Row:
-
10: Decomposed into \(5 + 5\)
- Explanation: The number 10 is split into two equal parts, each being 5.
-
24: Decomposed into \(20 + 4\)
- Explanation: The number 24 is split into a larger part (20) and a smaller part (4).
-
8: Decomposed into \(2 + 6\)
- Explanation: The number 8 is split into two parts, 2 and 6, which add up to 8.
2.
Middle Row:
-
6: Decomposed into \(3 + 3\)
- Explanation: The number 6 is split into two equal parts, each being 3.
-
7: Decomposed into \(5 + 2\)
- Explanation: The number 7 is split into a larger part (5) and a smaller part (2).
-
5: Decomposed into \(4 + 1\)
- Explanation: The number 5 is split into two parts, 4 and 1, which add up to 5.
3.
Bottom Row:
-
11: Decomposed into \(10 + 1\)
- Explanation: The number 11 is split into a larger part (10) and a smaller part (1).
-
4: Decomposed into \(3 + 1\)
- Explanation: The number 4 is split into two parts, 3 and 1, which add up to 4.
-
1: Decomposed into \(1 + 0\)
- Explanation: The number 1 is split into two parts, 1 and 0, which add up to 1.
#### General Observations:
-
Flexibility in Decomposition: Each number can be decomposed in multiple ways. For example, 10 can also be decomposed as \(6 + 4\) or \(7 + 3\), but the image shows one specific decomposition for each number.
-
Usefulness in Arithmetic: Decomposing numbers helps in mental math and simplifies calculations. For instance, adding 24 and 17 can be easier if you decompose 24 as \(20 + 4\) and then add accordingly.
-
Foundation for Place Value: Decomposing numbers often involves breaking them into tens and ones, which is crucial for understanding place value.
Final Answer:
The image demonstrates various ways to decompose numbers into smaller parts. Each decomposition shown adds up to the original number, illustrating the flexibility and utility of this mathematical concept.
\[
\boxed{\text{Decomposing numbers involves breaking them into smaller parts that add up to the original number.}}
\]
