Answer:
jbjkiu; 8227/8*cf hv
Step-by-step explanation:
The answer is -2.4, -0.8,0.2,0.9,1.6
x/20 = 21/14 (similar proportions)
x/20 = 3/2 (simplify by canceling out a factor of 7)
x = 30
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 answer: 98. So, if someone were to weigh 140 pounds, they would have around 98 pounds of water in their body!
