One way of reducing carbon dioxide in the atmosphere and slowing global warming is to plant trees which absorb carbon dioxide from the atmosphere.
A scientist plants some trees in the Amazon rainforest and the Tongass rainforest.
The scientist compares the carbon dioxide absorbed from the atmosphere by the trees she planted in the Amazon rainforest with the trees she planted in the Tongass rainforest.
Amazon
|
Carbon absorbed per tree |
\(\frac{1}{5}\) more than in the Tongass |
|
Number of trees planted |
\(\frac{1}{4}\) less than in the Tongass |
By what fraction is the total carbon dioxide absorbed by the trees planted in the Amazon compared with the total carbon dioxide absorbed by the trees planted in the Tongass rainforest?
