Solve the Fraction Equation: Finding the Missing Number in 7/14 + ? = 1/2

To solve this problem, we will focus on simplifying the fraction on the left side and comparing it to the fraction on the right side:

• Step 1: Simplify the fraction $\frac{7}{14}$. Since both 7 and 14 have a common factor of 7, we can divide both the numerator and denominator by 7 to get $\frac{1}{2}$.
• Step 2: We now have the equation $\frac{1}{2} + ? = \frac{1}{2}$.
• Step 3: To determine what needs to be added to $\frac{1}{2}$ to result in $\frac{1}{2}$, we can see that nothing needs to be added. Therefore, the unknown term $?$ should be 0.

This makes sense because adding zero to any number does not change its value.

Therefore, the solution to the problem is $0$.
