Final answer:
Christine watched videos for a total of 1/2 minute, by adding 3/8 minutes and 1/8 minutes to yield a simplified result of 1/2 minute.
Step-by-step explanation:
Christine watched one video for 3/8 minutes and another video for 1/8 minutes. To find out how long she watched videos in total, we need to perform addition with these fractions. Since both fractions have the same denominator, we simply add the numerators together:
- (3/8) minutes + (1/8) minutes = (3 + 1) / 8 minutes
- 4/8 minutes
This can be simplified, as 4/8 is equivalent to 1/2. Therefore, Christine watched videos for a total of 1/2 minutes.
