A mixed number is a combination of two numbers: a whole number and a proper fraction (A proper fraction is a fraction which has a denominator that is greater than the numerator, i.e., \(\frac{3}{7}\), \(\frac{9}{13}\), etc.). Moreover, a mixed number can be converted into a fraction and it always lies between two whole numbers.
For example, let’s take the mixed number \(3 \frac{1}{6}\). This mixed number comprises two parts: a whole number which is 3 and a proper fraction which is \(\frac{1}{6}\). If we convert this mixed number into an improper fraction, which is \(\frac{19}{6}\), we find that it lies between the two whole numbers 3 and 4. Some other examples of a mixed number are \(2 \frac{1}{2}\), \(3 \frac{1}{3}\), \(4 \frac{1}{5}\), etc.
Parts of a Mixed Number
A mixed number consists of three distinct parts: a whole number, a numerator, and a denominator. Here, the numerator and the denominator are parts of the proper fraction.
How to Convert Improper Fractions to Mixed Numbers
- First, divide the numerator of the fraction by the denominator.
- Next, write down the quotient as the whole number of the mixed fraction.
- Now, the remainder becomes the numerator and the divisor becomes the denominator of the improper part.
For example, let’s take the improper fraction \(\frac{7}{2}\). When we divide 7 by 2, the quotient is 3. The remainder is 1, and the divisor is 2. So, the mixed number is \(3 \frac{1}{2}\).
Steps to Add Mixed Numbers
- First, add the whole parts separately and the fractional parts separately.
- Next, simplify your answer and write it in the lowest terms.
For example, let’s add \(4 \frac{1}{3} + 2 \frac{1}{5}\). The addition is: \((4 + 2) + \left(\frac{1}{3} + \frac{1}{5}\right) = 6 + \left(\frac{5 \cdot 1 + 1 \cdot 3}{5 \cdot 3}\right) = 6 + \frac{8}{15}\).
