Solve the Fraction Equation: Finding the Missing Addend in 3/6 + ? = 4/6

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

• Step 1: Subtract the original fraction from the resulting fraction.
• Step 2: Simplify the resulting fraction if needed.

Now, let's work through each step:

Step 1: Given the equation $\frac{3}{6} + x = \frac{4}{6}$, we solve for $x$ by subtracting $\frac{3}{6}$ from both sides:
$x = \frac{4}{6} - \frac{3}{6}$.

Step 2: Compute the subtraction:
Since both fractions have the same denominator, subtract the numerators: $4 - 3 = 1$. Thus, the fraction is $\frac{1}{6}$.

Therefore, the missing fraction is $\frac{1}{6}$.
