Solve the Fraction Equation: Finding the Missing Term in 2/3 - ? = 1/3

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

• Identify the fractions involved: $\frac{2}{3}$ and $\frac{1}{3}$.
• Recognize that the denominators are the same, which simplifies subtraction.
• Subtract the fraction $\frac{1}{3}$ from $\frac{2}{3}$ to determine the missing fraction.

Let’s calculate the missing fraction:

Given the equation:

$\frac{2}{3} - \text{missing fraction} = \frac{1}{3}$

Rearrange to solve for the missing fraction:

$\text{missing fraction} = \frac{2}{3} - \frac{1}{3}$

Because the fractions have a common denominator, subtract the numerators:

$\frac{2}{3} - \frac{1}{3} = \frac{2-1}{3} = \frac{1}{3}$

The missing fraction is thus $\frac{1}{3}$.

Therefore, the solution to the problem is $\frac{1}{3}$.
