How to slove multiply mixed number fractions
Solution
To solve multiplication problems involving mixed number fractions, you can follow these steps:
Step 1: Convert Mixed Numbers to Improper Fractions
A mixed number consists of a whole number and a fraction. To convert a mixed number to an improper fraction:
- Multiply the whole number by the denominator of the fraction.
- Add this result to the numerator of the fraction.
- The sum becomes the numerator of the improper fraction, and the denominator remains the same.
For example, for the mixed number :
Step 2: Multiply the Improper Fractions
Once you've converted all mixed numbers to improper fractions, multiply the fractions by:
- Multiplying the numerators together to get the new numerator.
- Multiplying the denominators together to get the new denominator.
For example, multiplying by :
Step 3: Simplify the Result (If Necessary)
If the fraction can be simplified, do so by finding the greatest common divisor (GCD) of the numerator and denominator and dividing both by it.
Step 4: Convert Back to a Mixed Number (If Necessary)
If the result is an improper fraction and you need to present it as a mixed number:
- Divide the numerator by the denominator to get the whole number part.
- The remainder becomes the numerator of the fractional part.
For example, converting back to a mixed number: Where 6 is the whole number (since remainder 7), and is the fraction part.
