Number of Dragonfly Species in Siberia

To determine the number of dragonfly species found in Siberia, we can use the information provided in the question. According to the question, there are 6,000 species of dragonflies worldwide, with 2/15 of all dragonfly species found in South America and 3/40 of all dragonfly species found in Siberia.

To calculate the number of dragonfly species in Siberia, we can use the following formula:

Number of dragonfly species in Siberia = (3/40) * (2/15) * 6,000

Let's calculate it step by step:

1. Multiply 2/15 by 6,000: (2/15) * 6,000 = 800

2. Multiply the result by 3/40: 800 * (3/40) = 60

Therefore, there are approximately 60 species of dragonflies found in Siberia.

Please note that the exact number of dragonfly species in Siberia may vary and could be subject to further research and study.
