### Instruction: Write $\cfrac{\cfrac{3}{8}+\cfrac{7}{8}}{\cfrac{4}{5}}$ as a simplified fraction.### Response: This problem involves adding fractions with the same denominator, and then dividing fractions.
To add fractions with the same denominator, I just need to add the numerators and keep the same denominator.
So $\cfrac{3}{8}+\cfrac{7}{8}=\cfrac{10}{8}$.
To divide fractions, I need to multiply by the reciprocal of the second fraction.
So $\cfrac{\cfrac{10}{8}}{\cfrac{4}{5}}=\cfrac{10}{8}\times\cfrac{5}{4}$.
To multiply fractions, I need to multiply the numerators and the denominators.
So $\cfrac{10}{8}\times\cfrac{5}{4}=\cfrac{50}{32}$.
To simplify a fraction, I need to divide the numerator and the denominator by their greatest common factor.
The greatest common factor of 50 and 32 is 2.
So $\cfrac{50}{32}=\cfrac{50\div 2}{32\div 2}=\cfrac{25}{16}$.
