Question

Дети собрали 20 кг лекарственных трав. Из них1/6 составляет зверобой,1/5-тысячелистник,1/3-мята,а остальную часть-календула.Сколько килограммов календулы собрали дети?

Answer 1

1/6+1/5+1/3=5/30+6/30+10/30=21/30

30/30-21/30=9/30=3/10

20*3/10=6кг календулы собрали дети

Answer 2

1)  1/6+1/5+1/3=находим общий знаминатель= ( (1х5)+(1х6)+(1х10) )/30=21/30 части - звероб, тысяч., мята

2) берём общее кол-во лекарст трав, как цело равное еденице ( 1) 

1-21/30= находим общий знаменатель= ( (1х30)- (21х1) )/30= 9/30= сокращаем на 3= 3/10 части  календулы

3)  20:10х2=6 (кг) календулы

Ответ: 6 кг. календулы собрали дети

Calculating the Amount of Calendula Collected by Children

To calculate the amount of calendula collected by the children, we can follow these steps:

1. Calculate the Fraction of Calendula Collected: - The children collected a total of 20 kg of medicinal herbs. - Of this total, 1/6 is represented by St. John's wort, 1/5 by yarrow, and 1/3 by mint, leaving the rest for calendula. - We need to find the amount of calendula collected.

2. Determine the Amount of Calendula: - First, we calculate the combined fraction of St. John's wort, yarrow, and mint: 1/6 + 1/5 + 1/3 = 21/30 = 7/10. - Then, we find the fraction representing the remaining amount for calendula: 1 - 7/10 = 3/10. - Finally, we calculate the weight of calendula collected: 20 kg * 3/10 = 6 kg.

So, the children collected 6 kilograms of calendula.

This calculation is based on the provided fractions and the total weight of medicinal herbs collected.
