Answer 1

there is 8 pints of blood for every 14 pounds of body weight

Answer 2

`1` units.

Explanation:

Here body weight is 14 pounds =
`(14)/(2.205)` kg =
`6.35` kg (∵ 1 kg ≈ 2.205 ponds ).

Normally, 75 ml of blood needs, if the body weight is 1 kg. Therefore total amount of blood for the body weight 14 pounds
`(6.35 kg) = 6.35*75 ml=476.25 ml`
`=.47625 l` and we know that 1 litter of blood =2.11338 point of blood.

Hence total amount of blood =
`0.47625*2.11338` points =
`1.006497` units≈
`1` units.
