Understanding the Problem

When dealing with fractions, it's essential to understand how to simplify them and write products as mixed numbers. In this article, we will explore how to shade a model to help us find the product of two fractions and then write the result as a mixed number.

Shading the Model

To begin, let's consider the problem 2Γ—782 \times \frac{7}{8}. We can represent this product using a model, such as a rectangular array or a grid. The model will help us visualize the product and make it easier to calculate.

Step 1: Draw the Model

Draw a rectangular array with 2 rows and 8 columns. This will represent the product of 2 and 78\frac{7}{8}.

Step 2: Shade the Model

Shade 7 out of the 8 columns in each row. This will represent the fraction 78\frac{7}{8}.

Step 3: Count the Shaded Columns

Count the total number of shaded columns in the entire array. Since there are 2 rows, and each row has 7 shaded columns, the total number of shaded columns is 2 x 7 = 14.

Step 4: Write the Product as a Mixed Number

Now that we have counted the total number of shaded columns, we can write the product as a mixed number. A mixed number is a combination of a whole number and a fraction. In this case, the whole number part is 1 (since 8 x 1 = 8), and the fraction part is 68\frac{6}{8} (since 14 - 8 = 6).

Therefore, the product 2Γ—782 \times \frac{7}{8} can be written as a mixed number: 1 68\frac{6}{8}.

Simplifying the Fraction

We can simplify the fraction 68\frac{6}{8} by dividing both the numerator and the denominator by their greatest common divisor, which is 2. This gives us 34\frac{3}{4}.

Therefore, the product 2Γ—782 \times \frac{7}{8} can be written as a simplified mixed number: 1 34\frac{3}{4}.

Conclusion

In this article, we learned how to shade a model to help us find the product of two fractions and then write the result as a mixed number. We used a rectangular array to represent the product and shaded 7 out of 8 columns in each row to represent the fraction 78\frac{7}{8}. We then counted the total number of shaded columns and wrote the product as a mixed number. Finally, we simplified the fraction by dividing both the numerator and the denominator by their greatest common divisor.

Key Takeaways

  • To simplify fractions, divide both the numerator and the denominator by their greatest common divisor.
  • To write products as mixed numbers, count the total number of shaded columns in the model and write the result as a combination of a whole number and a fraction.
  • Shading a model can help us visualize the product and make it easier to calculate.

Q: What is a fraction?

A: A fraction is a way to represent a part of a whole. It consists of a numerator (the top number) and a denominator (the bottom number). For example, 12\frac{1}{2} represents one half of a whole.

Q: What is a mixed number?

A: A mixed number is a combination of a whole number and a fraction. For example, 1 34\frac{3}{4} represents one whole and three quarters.

Q: How do I simplify a fraction?

A: To simplify a fraction, divide both the numerator and the denominator by their greatest common divisor (GCD). For example, to simplify 68\frac{6}{8}, divide both numbers by 2 to get 34\frac{3}{4}.

Q: How do I write a product as a mixed number?

A: To write a product as a mixed number, count the total number of shaded columns in the model and write the result as a combination of a whole number and a fraction. For example, to write the product 2Γ—782 \times \frac{7}{8} as a mixed number, count the total number of shaded columns (14) and write the result as 1 68\frac{6}{8}.

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. For example, the GCD of 6 and 8 is 2.

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

A: To find the GCD of two numbers, list the factors of each number and find the largest factor they have in common. For example, the factors of 6 are 1, 2, 3, and 6, and the factors of 8 are 1, 2, 4, and 8. The largest factor they have in common is 2.

Q: What is the difference between a fraction and a decimal?

A: A fraction is a way to represent a part of a whole, while a decimal is a way to represent a number as a sum of powers of 10. For example, 12\frac{1}{2} is equal to 0.5.

Q: How do I convert a fraction to a decimal?

A: To convert a fraction to a decimal, divide the numerator by the denominator. For example, to convert 12\frac{1}{2} to a decimal, divide 1 by 2 to get 0.5.

Q: How do I convert a decimal to a fraction?

A: To convert a decimal to a fraction, express the decimal as a sum of powers of 10 and then simplify the resulting fraction. For example, to convert 0.5 to a fraction, express it as 510\frac{5}{10} and then simplify to 12\frac{1}{2}.
