Adding Fractions: Calculate 1/8 + 6/8 Hour of Homework Time

To solve the problem of determining how long Ned spends doing his homework, we need to add the times he spent on language and science homework.

Given:
- Language homework: $\frac{1}{8}$ of an hour
- Science homework: $\frac{6}{8}$ of an hour

Since both times have the same denominator, adding them is straightforward:

$\frac{1}{8} + \frac{6}{8} = \frac{1+6}{8} = \frac{7}{8}$

Therefore, Ned spends $\frac{7}{8}$ of an hour doing his homework.
