Explanation:

Step1: Calculate ocean water share

Oceans are salt water, which is 97% of all Earth's water.

Step2: Calculate total fresh water share

Fresh water is 3% of all Earth's water, so this is the total of all fresh sources.

Step3: Calculate glaciers share

Glaciers are 69.4% of fresh water: $0.03 \times 0.694 = 0.02082$, or 2.082% of all Earth's water.

Step4: Calculate groundwater share

Groundwater is 30.1% of fresh water: $0.03 \times 0.301 = 0.00903$, or 0.903% of all Earth's water.

Step5: Calculate surface water share

Surface water is less than 1% of fresh water, so $0.03 \times 0.01 = 0.0003$, or 0.03% (max) of all Earth's water.

Step6: Calculate lakes share

Lakes are 87% of surface water: $0.0003 \times 0.87 = 0.000261$, or 0.0261% of all Earth's water.
