Introduction to Mixed Numbers and Multiplication

In mathematics, mixed numbers are a combination of a whole number and a fraction. They are often used to represent quantities that are not whole, but can be expressed as a sum of a whole number and a fraction. In this article, we will focus on calculating the product of a mixed number and a whole number, specifically ${ $2 \frac{3}{8} \times 4\$}$ .

To begin, let's break down the mixed number ${$2 \frac{3}{8}$. The whole number part is 2, and the fraction part is [\frac{3}{8}$. To multiply a mixed number by a whole number, we can multiply the whole number part of the mixed number by the whole number, and then multiply the fraction part of the mixed number by the whole number.

Multiplying the Whole Number Part

The whole number part of the mixed number is 2, and the whole number we are multiplying by is 4. To multiply these two whole numbers, we simply multiply them together.

2 × 4 = 8

Multiplying the Fraction Part

The fraction part of the mixed number is [\frac{3}{8}$, and we are multiplying it by the whole number 4. To multiply a fraction by a whole number, we multiply the numerator (the top number) by the whole number, and then keep the denominator (the bottom number) the same.

3 × 4 = 12

So, the fraction part of the mixed number becomes [\frac{12}{8}$.

Simplifying the Fraction

The fraction [\frac{12}{8}$ can be simplified by dividing both the numerator and the denominator by their greatest common divisor (GCD). The GCD of 12 and 8 is 4.

12 ÷ 4 = 3 8 ÷ 4 = 2

So, the simplified fraction is [\frac{3}{2}$.

Combining the Whole Number Part and the Simplified Fraction

Now that we have the product of the whole number part (8) and the simplified fraction [\frac{3}{2}$, we can combine them to get the final answer.

8 + [\frac{3}{2}}$

To add a whole number and a fraction, we need to find a common denominator for the whole number and the fraction. In this case, the common denominator is 2.

8 = ${\frac{16}{2}}$

Now we can add the whole number and the fraction:

${\frac{16}{2}}$ + ${\frac{3}{2}}$ = ${\frac{19}{2}}$

Conclusion

In conclusion, the product of $ $2 \frac{3}{8} \times 4\$}$ is ${\frac{19}{2}$. This can be written as a mixed number **9 \frac{1{2}$.

Final Answer

The final answer is: **9 \frac{1}{2}$.

Examples

Example 1: Multiplying a Mixed Number by a Whole Number

[ $2 \frac{3}{8} \times 4}$

To solve this problem, we multiply the whole number part of the mixed number by the whole number, and then multiply the fraction part of the mixed number by the whole number.

2 × 4 = 8 3 × 4 = 12

So, the product of ${ $2 \frac{3}{8} \times 4}$ is ${\frac{12}{8}$.

Example 2: Simplifying a Fraction

[\frac{12}{8}}$

To simplify this fraction, we divide both the numerator and the denominator by their greatest common divisor (GCD).

12 ÷ 4 = 3 8 ÷ 4 = 2

So, the simplified fraction is ${\frac{3}{2}$.

Example 3: Adding a Whole Number and a Fraction

[\frac{3}{2} + 2}$

To solve this problem, we find a common denominator for the whole number and the fraction. Then, we add the numerators and keep the denominator the same.

2 = ${\frac{4}{2}}$

So, the sum of ${\frac{3}{2} + 2}$ is [\frac{7}{2}$.

Conclusion

In conclusion, mixed numbers and multiplication can be a bit tricky, but with practice and patience, you can become proficient in solving these types of problems. Remember to multiply the whole number part of the mixed number by the whole number, and then multiply the fraction part of the mixed number by the whole number. Don't forget to simplify the fraction and add the whole number and the fraction if necessary.

Final Answer

The final answer is: **9 \frac{1}{2}$.
