Question

Гноми зібрали 84 кг.ягід.Ожина становила 1.4 від усіх ягід, жовта малина -1.7, а решту червона малина .Скільки кілограмів окремо ожини ,жовтої та червоної малини зібрали гноми.

Answer 1

84:4*1=21 кг ожини
84:7*1=12 кг жовтої малини
21+12=33 кг ожини та жовтої малини разом
84-33=51 кг червоної малини

Answer 2

Calculating the Amount of Each Berry

The gnomes collected a total of 84 kg of berries. Of these, 1.4 times the amount was elderberries, 1.7 times the amount was yellow raspberries, and the rest was red raspberries. To find out how many kilograms of each type of berry were collected, we can use algebraic equations.

Let's represent the amount of elderberries as E, the amount of yellow raspberries as Y, and the amount of red raspberries as R.

We know the following: - E + Y + R = 84 (the total amount of berries is 84 kg) - E = 1.4R (elderberries are 1.4 times the amount of red raspberries) - Y = 1.7R (yellow raspberries are 1.7 times the amount of red raspberries)

We can use these equations to solve for the amounts of each type of berry.

Solving for the Amount of Each Berry

First, we can substitute the expressions for E and Y in terms of R into the total amount equation:

1.4R + 1.7R + R = 84 4.1R = 84 R = 84 / 4.1 R ≈ 20.49

Now that we have the amount of red raspberries, we can find the amounts of elderberries and yellow raspberries:

E = 1.4 * 20.49 ≈ 28.69 kg Y = 1.7 * 20.49 ≈ 34.83 kg

Conclusion

The gnomes collected approximately 28.69 kg of elderberries, 34.83 kg of yellow raspberries, and 20.49 kg of red raspberries.
