Question:

A car emits 3,254 kg of carbon dioxide into the environment each year. A hybrid car emits 2,308 kg of carbon dioxide in the environment each year. What percentage of the conventional car's carbon dioxide is emitted by the hybrid car each year?

Answers

I found #71%#

Explanation:

You can think that a fraction in "real" world correspods to the same fraction in "%" world;
so you have:

#(3,254)/(2,308)=(100%)/(x%)#

rearranging:

#x%=100%(2,308)/(3,254)=70.9%~~71%#
