Rain forests are home to 90,000 of the 2,50,000 identified plant species in the world. What percent of the world’s identified plant species are found in rainforests

Solution:

Number of identified plant species in the world = 2,50,000

Number of identified plant species in the rain forests = 90,000

Percentage of identified plant species in rainforests = [(no. of plant species in rainforests)/(Total no. of plant species in the world)] × 100

= [90,000/2,50,000] × 100

= 900/25

= 36%

✦ Try This: Rain forests are home to 100,000 of the 2,25,000 identified plant species in the world. What percent of the world’s identified plant species are found in rainforests?

Number of identified plant species in the world = 2,25,000

Number of identified plant species in the rain forests = 1,00,000

% of identified plant species in rainforests =

[(no. of plant species in rainforests)/(Total no. of plant species in the world)] × 100

= [1,00,000/2,25,000] × 100

= 10000/225

= 44.44%
