Question

Rye bread contains 3/250 fat, 13/25 protein, and 9/20 carbohydrates. Butter contains 4/5fat, 1/250 protein, and 1/200 carbohydrates. How much fat, protein, and carbohydrates are in 5kg of bread, and how much is there in 500g of butter?

Answer 1

In Rye bread: 3/50 kg fat, 13/5 kg protein, and 9/4kg carbohydrates.

In butter: 400g fats, 2g proteins, and 2.5 g carbohydrates.

Explanation:

The amount of fat in 5kg Rye bread is

`(3)/(250) *(5kg) = \boxed{(3)/(50) kg}`

, the amount of protein is

`(13)/(25)*(5kg)= \boxed{(13)/(5) kg }`

and the amount of carbohydrates are

`(9)/(20)*(5kg)= \boxed{(9)/(4) kg }`

Similarly, the amount of fat in 500g of butter is

`(4)/(5)*(500g)= \boxed{400g }`

the amount of proteins is

`(1)/(250)*(500g)= \boxed{2g }`

and the amount of carbohydrates is

`(1)/(200)*(500g)= \boxed{2.5g }`
