Solve the Fraction Equation: Finding the Missing Term in 5/15 + ? + 3/15 = 13/15

The goal is to find the missing fraction in the equation $\frac{5}{15} + \_ + \frac{3}{15} = \frac{13}{15}$.

To find the missing fraction, observe the following:
- Start by focusing only on the numerators because they have the same denominator.

We write the equation for the numerators:

• $5 + x + 3 = 13$

Combine the known terms on the left side, $5 + 3$, which results in 8:

• $8 + x = 13$

Now, solve for $x$ by subtracting 8 from both sides:

• $x = 13 - 8$
• $x = 5$

The missing fraction is $\frac{x}{15} = \frac{5}{15}$.

Therefore, the missing fraction that completes the equation is $\frac{5}{15}$.
