Introduction to Mixed Numbers
Mixed numbers are a combination of a whole number and a fraction. For example, 5 5/8 consists of the whole number 5 and the fraction 5/8. Understanding mixed numbers is essential because they appear frequently in real-life scenarios, such as cooking, construction, and finance.
When performing operations like addition, subtraction, multiplication, or division, mixed numbers often need to be converted into improper fractions. An improper fraction is a fraction where the numerator (top number) is greater than or equal to the denominator (bottom number). For instance, 5 5/8 can be converted into 45/8.
Why is this conversion important? Working with improper fractions simplifies calculations, especially when dividing by whole numbers or other fractions. Let’s explore how this process works in the next section.
Step-by-Step Solution to 5 5/8 Divided by 2
To solve 5 5/8 divided by 2, follow these steps:
- Convert the mixed number to an improper fraction: As mentioned earlier, 5 5/8 becomes 45/8.
- Write the division as a fraction: Dividing by 2 is the same as multiplying by its reciprocal. So, 45/8 ÷ 2 becomes 45/8 × 1/2.
- Multiply the numerators and denominators: Multiply 45 by 1 (numerator) and 8 by 2 (denominator). This gives you 45/16.
- Simplify the result: Convert the improper fraction 45/16 back into a mixed number, which is 2 13/16.
Thus, the final answer to 5 5/8 divided by 2 is 2 13/16.
Converting Mixed Numbers to Improper Fractions
Converting mixed numbers to improper fractions is a crucial skill. Here’s how it works:

- Multiply the whole number by the denominator of the fraction.
- Add the result to the numerator of the fraction.
- Write the sum as the new numerator, keeping the same denominator.
For example, to convert 5 5/8:
- 5 × 8 = 40
- 40 + 5 = 45
- The improper fraction is 45/8.
The Basics of Dividing Fractions
Dividing fractions involves a simple rule: multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a number is obtained by flipping its numerator and denominator. For example, the reciprocal of 2 is 1/2.
When dividing a fraction by a whole number, treat the whole number as a fraction with a denominator of 1. For instance, 2 can be written as 2/1. Its reciprocal is 1/2.
This principle applies to our problem: 45/8 ÷ 2 becomes 45/8 × 1/2, resulting in 45/16.
Simplifying the Results
After performing the division, simplify the result if necessary. To convert an improper fraction like 45/16 into a mixed number:
- Divide the numerator by the denominator: 45 ÷ 16 = 2 with a remainder of 13.
- Write the quotient (2) as the whole number.
- Write the remainder (13) as the numerator of the fraction, keeping the same denominator (16).
The simplified result is 2 13/16.
Practical Examples and Applications
Fraction division is not just a theoretical concept; it has practical applications in everyday life. Here are some examples:
- Cooking: Recipes often require dividing ingredients, such as halving a recipe that calls for 5 5/8 cups of flour.
- Construction: Builders may need to divide measurements, like cutting a 5 5/8-inch board into two equal parts.
- Finance: Budgeting and splitting expenses often involve dividing amounts, such as dividing a $5.625 bill between two people.
Understanding how to divide fractions ensures accuracy in these scenarios.
Common Mistakes to Avoid
While solving fraction division problems, people often make these mistakes:
- Forgetting to convert mixed numbers: Always convert mixed numbers to improper fractions before dividing.
- Incorrectly finding reciprocals: Remember to flip the numerator and denominator when finding the reciprocal.
- Skipping simplification: Always simplify the result to its lowest terms or convert it back to a mixed number if needed.
By being mindful of these pitfalls, you can ensure accurate calculations.
