Question

Провитамина А в 1 кг куриных яиц на 4 мг больше , чем витамина РР найдите, сколько каждого витамина в 500 г яиц, учитывая, что содержимое провитамина А в 3 раза больше.

Answer 1

Составим пропрцию. Пусть х - провитамин пп, тлшда х+4 - провитамин А
Пропорция: 0,5(х+4)\0,5х=3 (0,5 сократим, хперенесем в левую часть домножив 2 уравнения на х)
х+4=3х
3х-х=4
х(3-1)=4
х=2
значит витамин А=2+4=6
Ответ: витамина рр 2 мг а витамина А 6

Answer 2

Calculation of Vitamin A and Vitamin B3 in 500g of Eggs

To calculate the amount of each vitamin in 500g of eggs, we'll use the given information that the provitamin A content is three times more than the vitamin B3 content in 1kg of eggs.

Given: - Provitamin A in 1kg of eggs = 4mg more than Vitamin B3 - Provitamin A content is three times more than Vitamin B3 content

Let's denote the amount of Vitamin B3 as x mg. Then the amount of Provitamin A would be 4mg + x mg.

Since the Provitamin A content is three times more than the Vitamin B3 content, we can set up the equation: 4mg + x = 3x

Solving for x: 4mg = 2x x = 2mg

So, the amount of Vitamin B3 in 1kg of eggs is 2mg, and the amount of Provitamin A is 4mg + 2mg = 6mg.

Now, to find the amount of each vitamin in 500g of eggs, we can simply divide these values by 2:

In 500g of eggs: - Provitamin A: 6mg / 2 = 3mg - Vitamin B3: 2mg / 2 = 1mg

Therefore, in 500g of eggs, there are 3mg of Provitamin A and 1mg of Vitamin B3.
