Step-by-Step Solution

To solve the addition of the fractions 46+18 \frac{4}{6} + \frac{1}{8} , we will first find the least common denominator.

  • The denominators of the fractions are 6 and 8. To add these fractions, we need a common denominator.
  • Calculate the least common multiple (LCM) of 6 and 8:
    • Prime factorization of 6: 6=2×3 6 = 2 \times 3 .
    • Prime factorization of 8: 8=23 8 = 2^3 .
    • The LCM will take the highest power of each prime that appears in these factorizations: 23×3=24 2^3 \times 3 = 24 .
  • Convert each fraction to an equivalent fraction with 24 as the denominator:
    • Convert 46 \frac{4}{6} : Multiply both the numerator and denominator by 4 (since 246=4 \frac{24}{6} = 4 ): 4×46×4=1624\frac{4 \times 4}{6 \times 4} = \frac{16}{24}.
    • Convert 18 \frac{1}{8} : Multiply both the numerator and denominator by 3 (since 248=3 \frac{24}{8} = 3 ): 1×38×3=324\frac{1 \times 3}{8 \times 3} = \frac{3}{24}.
  • Now, add these two fractions:
    • 1624+324=16+324=1924\frac{16}{24} + \frac{3}{24} = \frac{16 + 3}{24} = \frac{19}{24}.

Thus, the sum of the fractions 46 \frac{4}{6} and 18 \frac{1}{8} is 1924\frac{19}{24}.

The correct choice from the available options is 1924\frac{19}{24}.

Therefore, the solution to the problem is 1924 \frac{19}{24} .

Answer

1924 \frac{19}{24}
