Understanding Mixed Numbers
Before diving into multiplication, it's crucial to understand what mixed numbers are. A mixed number consists of:
- A whole number (e.g., 2 in 2 1/2)
- A proper fraction (e.g., 1/2 in 2 1/2)
Mixed numbers can be converted into improper fractions for easier calculations, which is a fundamental step when multiplying them.
Converting Mixed Numbers to Improper Fractions
To convert a mixed number into an improper fraction, follow these steps:
1. Multiply the whole number by the denominator of the fraction.
2. Add the result to the numerator of the fraction.
3. Place this total over the original denominator.
For example, to convert 2 1/3:
1. Multiply: \(2 \times 3 = 6\)
2. Add: \(6 + 1 = 7\)
3. Place over the denominator: \( \frac{7}{3} \)
Therefore, 2 1/3 can be expressed as \( \frac{7}{3} \).
Multiplying Mixed Numbers
When multiplying mixed numbers, the process involves converting them into improper fractions, then multiplying those fractions, and finally converting back to a mixed number if necessary.
Step-by-Step Process
1. Convert both mixed numbers to improper fractions.
2. Multiply the numerators together.
3. Multiply the denominators together.
4. Simplify the resulting fraction, if possible.
5. Convert back to a mixed number if required.
Example of Multiplying Mixed Numbers
Let’s multiply 1 2/5 and 3 1/2:
1. Convert to improper fractions:
- \(1 2/5 = \frac{7}{5}\)
- \(3 1/2 = \frac{7}{2}\)
2. Multiply the numerators: \(7 \times 7 = 49\)
3. Multiply the denominators: \(5 \times 2 = 10\)
4. The resulting fraction is \( \frac{49}{10} \).
5. Convert to a mixed number: \(49 ÷ 10 = 4\) remainder 9, so \(4 \frac{9}{10}\).
