The human body is 70% water on average. about how much water will be in a person that weighs 140 pounds?

For this, you would need to find 70% of 140. To do so you must do the following: 140 x 0.7, which would lead you to the following 98. So, if someone were to weigh 140 pounds, they would have around 98 pounds of water in their body!
I hope this was helpful, and if you need any more help, please let me know so I can further assist you.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
