The image contains a math worksheet with problems involving fractions. The main question is implied by the format of the problems presented.

$$2\frac{5}{8} = \frac{(2 \times 8) + 5}{8} = \frac{16 + 5}{8} = \frac{21}{8}$$ $$1\frac{3}{8} = \frac{(1 \times 8) + 3}{8} = \frac{8 + 3}{8} = \frac{11}{8}$$

Since they already have a common denominator, subtract the numerators.

$$\frac{21}{8} - \frac{11}{8} = \frac{21 - 11}{8} = \frac{10}{8}$$

$$\frac{10}{8} = \frac{5}{4}$$ $$5 \div 4 = 1 \text{ with a remainder of } 1$$

So, $\frac{5}{4} = 1\frac{1}{4}$.

The final answer is $1\frac{1}{4}$.
