Answer:
17,164 species.
Step-by-step explanation:
We have been given that the IUCN Red List of threatened Species notes that 36% of the 47,677 species assessed are threatened with extinction.
To find the number of species that are threatened with extinction we will find 36% of 47,677.
![\text{Number of currently threatened species}=(36)/(100) * 47677](https://img.qammunity.org/2019/formulas/mathematics/high-school/e4a97julugmoc5skwuj02sqd1cmhwzbhuq.png)
![\text{Number of currently threatened species}=0.36* 47677](https://img.qammunity.org/2019/formulas/mathematics/high-school/tt8nk59r6brqwr7lnscyjcg0ua1m02778j.png)
![\text{Number of currently threatened species}=17163.72\approx 17164](https://img.qammunity.org/2019/formulas/mathematics/high-school/e8ja4rclkhpwp33cvaw09j48hlscdqvtwj.png)
Therefore, 171164 species are currently threatened with extinction.
