Explain how complex fractions can be used to solve problems involving ratios
Biologists study life at all levels of organization and complexity:Atoms
Genes
Atoms
Molecules
Cells
Tissues
Organs
Organisms
Populations
Communities
Ecosystems
Earth
Solar Systems
Galaxies
They can also study specific things within those classifications, such as specific organs, the effects of pollution on ecosystems, etc.
by you thinking out your awnser to complex fractions you will get part of you ratios or the awnser to your ratios
