Adult

An adult person should drink on average 2.5 litres of liquids per day and sleep 7 hours. He works 8 hours daily. The diet should consist of three nutrients: proteins, carbohydrates, and fats. Per 1 kg of body weight of an adult, these are 2 g of proteins, 4.5 g of carbohydrates, and 1.5 g of fats daily.

Express as a fraction in basic form:
A, what part of the day does an adult work?
B, how much liquid should an adult drink daily?
C, what part of the day should an adult sleep?
D, a person weighing 50 kg received 14 g of proteins. What part of the daily dose of proteins is this?
E, what part of the daily dose of the three mentioned nutrients is made up by fat?

Final Answer:

a =  1/3
b =  1/34
c =  7/24
d =  7/50
e =  3/16

Step-by-step explanation:

$a=\frac{8}{24}=\frac{1}{3}=0.3333$

$b=\frac{2.5}{85}=\frac{1}{34}=0.0294$

$c=\frac{7}{24}=0.2917$

$d=\frac{14}{50\cdot 2}=\frac{7}{50}=0.14$

$e=\frac{1.5}{2+4.5+1.5}=\frac{3}{16}=0.1875$
