Okay, so first let's note down the points we've in the question.

• Fraction of body weight that's water = 7/10
• Weight of the person = 140 pounds.
• Number of pounds that's water = ?

To find how many pounds of the person who weighs 140 pounds is water, we need to multiply 140 into 7/10.

⇨ Let's solve it now.

`\sf \: 140 * (7)/(10) \\ \sf = 14 \bcancel{0} * \frac{7}{1 \bcancel{0}} \\ \sf = 14 * 7 \\ = \boxed{\boxed{\bf \: 98 \: pounds}}`

• A person who weighs 140 pounds will be approximately 98 pounds water.
