Answer:
A: 4 articles
B: 12 articles
C: 20 articles
Explanation:
The ratio of articles shared among A, B, and C is 1:3:5, which means that A gets 1 part, B gets 3 parts, and C gets 5 parts. If we let the ratio be x:3x:5x, then A gets x articles, B gets 3x articles, and C gets 5x articles.
Since the total number of articles is 36, we can set up the following equation:
x + 3x + 5x = 36
Combining like terms, we get:
9x = 36
Dividing both sides by 9, we get

x = 4
Therefore, A gets 4 articles, B gets 3 × 4 = 12 articles, and C gets 4 × 5 = 20 articles.
So, the answer is:
- A: 4 articles
- B: 12 articles
- C: 20 articles
