What fraction of Earth's water is found in oceans?

Explanation:
Most of Earth's water is saltwater stored in the oceans, about 97 percent of all Earth’s water. That leaves the remaining roughly 3 percent as freshwater, found in glaciers and ice caps, groundwater, lakes and rivers, and a small amount in the atmosphere and living things. So the fraction in oceans is about 97 percent. The other options would imply far less water in the oceans or none, which doesn’t match how Earth’s water is distributed.
