What is 21 divided by 2?
Dividing 21 by 2 is a simple arithmetic operation. It's a way to find out how many times 2 fits into 21. Here's how it works:
Understanding the Concept
- Division: Division is a mathematical operation that splits a number into equal parts.
- Dividend: The number being divided (in this case, 21).
- Divisor: The number that divides the dividend (in this case, 2).
- Quotient: The result of the division (the number of times the divisor fits into the dividend).
- Remainder: The amount left over after the division is complete.
Calculating 21 Divided by 2
21 divided by 2 can be represented as:
- 21 / 2
When you divide 21 by 2, you get:
- Quotient: 10
- Remainder: 1
Explanation
- 2 fits into 21 a total of 10 times (2 x 10 = 20).
- There is 1 left over (21 - 20 = 1).
Therefore, 21 divided by 2 equals 10 with a remainder of 1.
Practical Applications
This type of division is used in many real-life situations, such as:
- Sharing: If you have 21 cookies and want to share them equally with 2 friends, each person would get 10 cookies, and there would be 1 cookie left over.
- Measurement: If you have a piece of string that is 21 inches long and you need to cut it into pieces that are 2 inches long, you can cut 10 pieces, and you will have 1 inch of string left over.
Conclusion
In summary, 21 divided by 2 results in a quotient of 10 and a remainder of 1. This simple calculation demonstrates the concept of division and its practical applications in everyday life.
