\huge \boxed{\mathfrak{Question} \downarrow}

  • A study showed that 7/10 of the human body weight is water. If a person weighs 140 pounds, how many pounds is water?

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

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

  • Fraction of body weight that's water = <u>7</u><u>/</u><u>1</u><u>0</u>
  • Weight of the person = <u>1</u><u>4</u><u>0</u><u> </u><u>pounds.</u>
  • 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 \times  \frac{7}{10}  \\ \sf  =  14 \bcancel{0} \times  \frac{7}{1 \bcancel{0}}  \\  \sf = 14 \times 7 \\  =    \boxed{\boxed{\bf \: 98 \: pounds}}

  • A person who weighs 140 pounds will be approximately <u>9</u><u>8</u><u> </u><u>pounds</u><u> </u><u>water.</u>
