[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
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.
[tex] \sf \: 140 \times \frac{7}{10} \\ \sf = 14 \bcancel{0} \times \frac{7}{1 \bcancel{0}} \\ \sf = 14 \times 7 \\ = \boxed{\boxed{\bf \: 98 \: pounds}}[/tex]
- A person who weighs 140 pounds will be approximately 98 pounds water.
