Step-by-Step Solution

To solve the problem of adding the fractions 37+514+13 \frac{3}{7} + \frac{5}{14} + \frac{1}{3} , we follow these steps:

  • Step 1: Find the Least Common Denominator (LCD).
    We have denominators 7, 14, and 3. The least common multiple (LCM) of these numbers is 42.
  • Step 2: Convert each fraction to the equivalent fraction with denominator 42.
    • 37 \frac{3}{7} : Multiply both the numerator and the denominator by 6 to get 1842 \frac{18}{42} .
    • 514 \frac{5}{14} : Multiply both the numerator and the denominator by 3 to get 1542 \frac{15}{42} .
    • 13 \frac{1}{3} : Multiply both the numerator and the denominator by 14 to get 1442 \frac{14}{42} .
  • Step 3: Add the fractions.
    Now, we add the numerators of these fractions: 18+15+14=47 18 + 15 + 14 = 47 .
  • Final Result:
    The sum of the fractions is 4742 \frac{47}{42} .

Therefore, the final answer is 4742 \frac{47}{42} .

Answer

4742 \frac{47}{42}
