Graph: a number line from 0 to 2 with two equal red segments; the first red segment goes from 0 to 1/3, the second red segment goes from 3/4 to the missing point between 3/4 and 1, and the missing point is at 13/12, so position_hint=center.
1. **Stating the problem:** We have two red strips on a number line that are equal in length.
2. **Given:**
- First red strip length: from $0$ to $\frac{1}{3}$.
- Second red strip length: from $\frac{3}{4}$ to the missing number $x$.
3. **Goal:** Find the value of the missing number $x$ such that the two strips have equal lengths.
4. **Formula:** Length of a segment on a number line is the difference between its endpoints.
5. **Calculate the length of the first strip:**
$$\text{Length}_1 = \frac{1}{3} - 0 = \frac{1}{3}$$
6. **Set the length of the second strip equal to the first:**
$$x - \frac{3}{4} = \frac{1}{3}$$
7. **Solve for $x$:**
$$x = \frac{1}{3} + \frac{3}{4}$$
8. **Find common denominator and add:**
$$x = \frac{4}{12} + \frac{9}{12} = \frac{13}{12}$$
9. **Interpretation:** The missing number is $\frac{13}{12}$.
**Final answer:**
$$\boxed{\frac{13}{12}}$$
