💡 Analysis & Explanation
Finding Common Denominator ▼
To add fractions efficiently, all terms must share a common base. Here, the Least Common Multiple (LCM) for the denominators 8 and 16 is 16.
Fraction Conversion ▼
Convert the fractions with an 8 in the denominator: 3/8 becomes 6/16, 1/8 becomes 2/16, and the final 1/8 also becomes 2/16.
Addition Process ▼
The equation transforms to (6/16) + (2/16) + (5/16) + (2/16). Summing the numerators gives 6 + 2 + 5 + 2 = 15.
Conclusion ▼
The simplified final fraction is mathematically exactly 15/16.
