Mixed Number Addition
1. The problem is to add two mixed numbers: $4 \frac{4}{8}$ and $3 \frac{2}{6}$.
2. Convert each mixed number to an improper fraction.
- For $4 \frac{4}{8}$, multiply the whole number (4) by the denominator (8) and add the numerator (4):
$$4 \times 8 + 4 = 32 + 4 = 36$$
So, $4 \frac{4}{8} = \frac{36}{8}$.
- For $3 \frac{2}{6}$, multiply the whole number (3) by the denominator (6) and add the numerator (2):
$$3 \times 6 + 2 = 18 + 2 = 20$$
So, $3 \frac{2}{6} = \frac{20}{6}$.
3. Find a common denominator for the fractions $\frac{36}{8}$ and $\frac{20}{6}$.
- The denominators are 8 and 6.
- The least common denominator (LCD) of 8 and 6 is 24.
4. Convert each fraction to have the denominator 24.
- For $\frac{36}{8}$, multiply numerator and denominator by 3:
$$\frac{36 \times 3}{8 \times 3} = \frac{108}{24}$$
- For $\frac{20}{6}$, multiply numerator and denominator by 4:
$$\frac{20 \times 4}{6 \times 4} = \frac{80}{24}$$
5. Add the fractions:
$$\frac{108}{24} + \frac{80}{24} = \frac{188}{24}$$
6. Simplify the fraction $\frac{188}{24}$.
- Both numerator and denominator can be divided by 4:
$$\frac{188 \div 4}{24 \div 4} = \frac{47}{6}$$
7. Convert the improper fraction back to a mixed number.
- Divide 47 by 6:
$$47 \div 6 = 7 \text{ remainder } 5$$
- So the mixed number is $7 \frac{5}{6}$.
**Final answer:** $4 \frac{4}{8} + 3 \frac{2}{6} = 7 \frac{5}{6}$
