00:22 Let's calculate the multiplications
00:32 Let's add under the common denominator
00:38 Let's calculate the numerator
00:45 And this is the solution to the question

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Find the least common multiple (LCM) of the denominators: 5, 3, and 15.
  • Step 2: Convert each fraction to an equivalent fraction with the LCM as the common denominator.
  • Step 3: Add the numerators of the converted fractions.
  • Step 4: Simplify the resulting fraction if necessary.

Now, let's work through each step:

Step 1: The denominators are 5, 3, and 15. The LCM of these numbers is 15.

Step 2: Convert each fraction:

  • 35=3×35×3=915 \frac{3}{5} = \frac{3 \times 3}{5 \times 3} = \frac{9}{15}
  • 13=1×53×5=515 \frac{1}{3} = \frac{1 \times 5}{3 \times 5} = \frac{5}{15}
  • 215=215 \frac{2}{15} = \frac{2}{15}

Step 3: Add the numerators of the converted fractions:

915+515+215=9+5+215=1615 \frac{9}{15} + \frac{5}{15} + \frac{2}{15} = \frac{9 + 5 + 2}{15} = \frac{16}{15}

Step 4: The fraction 1615 \frac{16}{15} is already in simplest form.

Therefore, the solution to the problem is 1615 \frac{16}{15} .

Answer

1615 \frac{16}{15}
