In order to turn percent to a fraction, first, we write it as 48/100. Then, from there we simplify it to the simplest form.
48/100 = (48/4) / (100/4) = 12/25
So, 48% <span>expressed as a fraction in simplest form is 12/25.</span>
The answer is D, photosynthesis and respiration.
—Evidence—
Oxygen is a byproduct of photosynthesis and, correspondingly, carbon dioxide the byproduct of respiration.
Oxygen gives our cells the ability to break down food in order to get the energy we need to survive. Although other animals may use different organs to breathe with, they all get oxygen into their bodies through respiration.
