Step-by-Step Solution

To solve the problem of adding the two fractions 38\frac{3}{8} and 19\frac{1}{9}, follow these steps:

  • Step 1: Find the least common denominator (LCD) of the fractions. We calculate 8×9=728 \times 9 = 72. Thus, the LCD is 72.
  • Step 2: Convert each fraction to an equivalent fraction with the LCD as the new denominator.
    • For 38\frac{3}{8}, multiply the numerator and denominator by 9: 3×98×9=2772\frac{3 \times 9}{8 \times 9} = \frac{27}{72}.
    • For 19\frac{1}{9}, multiply the numerator and denominator by 8: 1×89×8=872\frac{1 \times 8}{9 \times 8} = \frac{8}{72}.
  • Step 3: Add the two fractions: 2772+872=27+872=3572\frac{27}{72} + \frac{8}{72} = \frac{27 + 8}{72} = \frac{35}{72}.
  • Step 4: Simplify the resulting fraction if possible. Here, 3572\frac{35}{72} is already in its simplest form.

Thus, the sum of 38\frac{3}{8} and 19\frac{1}{9} is 3572\frac{35}{72}.

Therefore, the solution to the problem is 3572\frac{35}{72}.
