Introduction
Division is a fundamental operation in mathematics that involves sharing a certain quantity into equal parts or groups. It is an essential concept in various mathematical disciplines, including arithmetic, algebra, and geometry. In this article, we will focus on calculating division operations with two decimal places and verifying the results. We will explore six different division problems, each with a unique set of numbers.
Division Operations with Two Decimal Places
When performing division operations with two decimal places, it is crucial to follow the correct order of operations and to ensure that the results are accurate. The order of operations is a set of rules that dictate the order in which mathematical operations should be performed. In division, the order of operations is as follows:
- Divide the numbers
- Round the result to two decimal places
Problem a) 137 ÷ 5
To calculate the result of 137 ÷ 5, we will follow the order of operations.
- Divide 137 by 5: 137 ÷ 5 = 27.4
- Round the result to two decimal places: 27.40
Therefore, the result of 137 ÷ 5 is 27.40.
Problem b) 147 ÷ 12
To calculate the result of 147 ÷ 12, we will follow the order of operations.
- Divide 147 by 12: 147 ÷ 12 = 12.25
- Round the result to two decimal places: 12.25
Therefore, the result of 147 ÷ 12 is 12.25.
Problem c) $4125 ÷ 6
To calculate the result of $4125 ÷ 6, we will follow the order of operations.
- Divide 4125 by 6: 4125 ÷ 6 = 686.67
- Round the result to two decimal places: 686.67
Therefore, the result of $4125 ÷ 6 is 686.67.
Problem d) 715 ÷ 7
To calculate the result of 715 ÷ 7, we will follow the order of operations.
- Divide 715 by 7: 715 ÷ 7 = 102.14
- Round the result to two decimal places: 102.14
Therefore, the result of 715 ÷ 7 is 102.14.
Problem e) 431 ÷ 24
To calculate the result of 431 ÷ 24, we will follow the order of operations.
- Divide 431 by 24: 431 ÷ 24 = 17.96
- Round the result to two decimal places: 17.96
Therefore, the result of 431 ÷ 24 is 17.96.
Problem f) $2157 ÷ 132
To calculate the result of $2157 ÷ 132, we will follow the order of operations.
- Divide 2157 by 132: 2157 ÷ 132 = 16.33
- Round the result to two decimal places: 16.33
Therefore, the result of $2157 ÷ 132 is 16.33.
Conclusion
In conclusion, division operations with two decimal places are an essential concept in mathematics. By following the correct order of operations and ensuring that the results are accurate, we can perform division operations with confidence. The six division problems explored in this article demonstrate the importance of mastering division operations with two decimal places. Whether you are a student, a teacher, or a professional, understanding division operations with two decimal places is crucial for success in mathematics and beyond.
