About \(\frac{7}{10}\) of the human body is water. How many pounds of water are in a person who weighs 120 pounds?
Answer (3)
The weight of water in a person's body can be determined by multiplying the total body weight by 0.7, since about 70% of the human body is water. So for a person weighing 120 pounds, 120 * 0.7 = 84 pounds of their weight is water. ;
7/10 = .70
120 * .70 = 84
84 pounds of blood in the body of an 120 pound person.
A person who weighs 120 pounds contains approximately 84 pounds of water, as about \frac{7}{10} of the human body is water. This demonstrates the essential role water plays in the human body. Water makes up a substantial portion of total body weight, which is critical for many bodily functions.
