Answer:
1. 64.5 lbs
2. 52.5 lbs
3. 40lbs
4. 60 lbs
5. 80 lbs
Step-by-step explanation:
To determine how much of a persons weight is water, multiply 3/4 by their weight.
1. weight of water = weight * 3/4
= 86 * 3/4
= 64.5 lbs
2. weight of water = weight * 3/4
= 70 * 3/4
= 52.5 lbs
3. weight of water = weight * 3/4
30 = weight * 3/4
Multiply by 4/3 on each side
30*4/3 = weight *3/4*4/3
40 = weight
4. weight of water = weight * 3/4
45 = weight * 3/4
Multiply by 4/3 on each side
45*4/3 = weight *3/4*4/3
60 = weight
5. weight of water = weight * 3/4
60 = weight * 3/4
Multiply by 4/3 on each side
60*4/3 = weight *3/4*4/3
80 = weight
