Understanding Mixed Fractions
A mixed fraction consists of a whole number and a proper fraction combined. For example, 2 3/4 is a mixed fraction, where 2 is the whole number and 3/4 is the proper fraction.
Steps to Convert Mixed Fractions to Improper Fractions
1. Identify the Whole Number and Fraction
- In the mixed fraction, separate the whole number from the fractional part.
2. Convert Whole Number to Fraction
- Convert the whole number into a fraction. Multiply the whole number by the denominator of the fractional part. For example, in 2 3/4, the whole number is 2 and the denominator is 4.
- Calculation: 2 * 4 = 8.
3. Add the Numerator of the Fraction
- Add the result from the previous step to the numerator of the fractional part. In this case, add 8 (from the whole number) to 3 (the numerator).
- Calculation: 8 + 3 = 11.
4. Form the Improper Fraction
- Place the sum obtained in the previous step over the original denominator. This gives you the improper fraction.
- Result: 11/4.
Example
For the mixed fraction 3 1/5:
- Whole number: 3
- Proper fraction: 1/5
Following the steps:
- Convert 3 to a fraction: 3 * 5 = 15
- Add the numerator: 15 + 1 = 16
- Result: 16/5 as the improper fraction.
