Introduction

In mathematics, division is a fundamental operation that involves finding the quotient of two numbers. When we divide one number by another, we are essentially finding how many times the divisor fits into the dividend. In this article, we will explore the concept of division and how to represent the result as a fraction or a mixed number.

Understanding Division

Division is the inverse operation of multiplication. When we divide two numbers, we are essentially finding the number that, when multiplied by the divisor, gives us the dividend. For example, if we divide 18 by 15, we are finding the number that, when multiplied by 15, gives us 18.

Representing Division as a Fraction or a Mixed Number

When we divide one number by another, we can represent the result as a fraction or a mixed number. A fraction is a way of representing a part of a whole, while a mixed number is a way of representing a whole number and a fraction together.

To represent a division as a fraction, we can use the following format:

\frac{\text{dividend}}{\text{divisor}}

For example, if we divide 18 by 15, we can represent the result as a fraction as follows:

\frac{18}{15}

However, this fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor (GCD). In this case, the GCD of 18 and 15 is 3, so we can simplify the fraction as follows:

\frac{18}{15} = \frac{6}{5}

Option A: $2 \frac{3}{15}$

Option A represents the result of dividing 18 by 15 as a mixed number. A mixed number is a way of representing a whole number and a fraction together. In this case, the mixed number is $2 \frac{3}{15}$ .

To convert the fraction $\frac{18}{15}$ to a mixed number, we can divide the numerator by the denominator and find the remainder. In this case, we can divide 18 by 15 as follows:

18 \div 15 = 1 \text{ with a remainder of } 3

So, we can represent the result as a mixed number as follows:

1 \frac{3}{15}

However, this is not the same as option A, which is $2 \frac{3}{15}$ . To see why this is not the correct answer, let's analyze the result of dividing 18 by 15.

Analyzing the Result

When we divide 18 by 15, we are essentially finding the number that, when multiplied by 15, gives us 18. In this case, the result is 1 with a remainder of 3. This means that 15 fits into 18 one time with a remainder of 3.

So, we can represent the result as a mixed number as follows:

1 \frac{3}{15}

However, this is not the same as option A, which is $2 \frac{3}{15}$ . To see why this is not the correct answer, let's analyze the result of dividing 18 by 15 in more detail.

Analyzing the Result in More Detail

To see why this is the correct answer, let's consider the following:

When we divide 18 by 15, we are essentially finding the number that, when multiplied by 15, gives us 18.
In this case, the result is 1 with a remainder of 3.
This means that 15 fits into 18 one time with a remainder of 3.

So, we can represent the result as a mixed number as follows:

1 \frac{3}{15}

Conclusion

In conclusion, the correct answer is option D, which is $1 \frac{3}{15}$ . This is because when we divide 18 by 15, we are essentially finding the number that, when multiplied by 15, gives us 18. In this case, the result is 1 with a remainder of 3. This means that 15 fits into 18 one time with a remainder of 3.

Introduction

In our previous article, we explored the concept of division and how to represent the result as a fraction or a mixed number. We also analyzed the result of dividing 18 by 15 and concluded that the correct answer is option D, which is $1 \frac{3}{15}$ .

In this article, we will provide a Q&A section to help clarify any doubts or questions that readers may have.

Q: What is the difference between a fraction and a mixed number?

A: A fraction is a way of representing a part of a whole, while a mixed number is a way of representing a whole number and a fraction together.

Q: How do I convert a fraction to a mixed number?

A: To convert a fraction to a mixed number, you can divide the numerator by the denominator and find the remainder. The whole number part is the result of the division, and the fraction part is the remainder divided by the denominator.

Q: How do I simplify a fraction?

A: To simplify a fraction, you can divide both the numerator and the denominator by their greatest common divisor (GCD). This will give you a simpler fraction that represents the same value as the original fraction.

Q: What is the greatest common divisor (GCD)?

A: The greatest common divisor (GCD) is the largest number that divides both the numerator and the denominator of a fraction without leaving a remainder.

Q: How do I find the GCD of two numbers?

A: To find the GCD of two numbers, you can use the Euclidean algorithm or simply list the factors of each number and find the largest common factor.

Q: What is the Euclidean algorithm?

A: The Euclidean algorithm is a method for finding the greatest common divisor (GCD) of two numbers. It involves repeatedly dividing the larger number by the smaller number and taking the remainder until the remainder is zero.

Q: How do I use the Euclidean algorithm to find the GCD of two numbers?

A: To use the Euclidean algorithm to find the GCD of two numbers, you can follow these steps:

Divide the larger number by the smaller number and take the remainder.
Replace the larger number with the smaller number and the smaller number with the remainder.
Repeat steps 1 and 2 until the remainder is zero.
The last non-zero remainder is the GCD of the two numbers.

Q: What is the final answer to the problem $$18 \div 15$$?

A: The final answer to the problem $$18 \div 15$$ is option D, which is $1 \frac{3}{15}$ .

Conclusion

In conclusion, we hope that this Q&A section has helped to clarify any doubts or questions that readers may have had about the problem $$18 \div 15$$. If you have any further questions or concerns, please don't hesitate to contact us.
