Question

Папа купил 3 дыни.Масса первой дыни равна 4 3/10 кг,что на 7/10кг больше массы второй дыни и на 1 8/10 кг меньше массы третьей дыни. Чему равна общая масса всех трех дынь, которые купил папа?

Answer 1

Ответ:

14 кг

Пошаговое объяснение:

4  3\10 - 7\10 = 3  6\10 (кг) весит вторая дыня

4  3\10 + 1  8\10 = 6  1\10 (кг) весит третья дыня

4 3\10 + 3 6\10 + 6 1\10 = 14 (кг) дынь куплено.

Answer 2

Solution:

To find the total mass of the three melons, we can add the masses of each melon together.

Let's denote: - Mass of the first melon as M1 = 4 3/10 kg - Mass of the second melon as M2 - Mass of the third melon as M3

We are given that: - The mass of the second melon is 7/10 kg less than the first melon: M2 = M1 - 7/10 - The mass of the third melon is 1 8/10 kg less than the first melon: M3 = M1 - 1 8/10

To find the total mass, we can add the masses of all three melons together: Total mass = M1 + M2 + M3

Let's calculate the mass of the second and third melons using the given information.

Calculations:

- Mass of the second melon, M2: - M2 = M1 - 7/10 - M2 = 4 3/10 - 7/10 - M2 = 4 3/10 - 7/10 - M2 = 4 2/10 kg

- Mass of the third melon, M3: - M3 = M1 - 1 8/10 - M3 = 4 3/10 - 1 8/10 - M3 = 4 3/10 - 1 8/10 - M3 = 2 5/10 kg

Now, we can find the total mass of all three melons by adding their masses together.

Total Mass:

- Total mass = M1 + M2 + M3 - Total mass = 4 3/10 + 4 2/10 + 2 5/10 - Total mass = 11 kg

Answer:

The total mass of all three melons that the father bought is 11 kilograms.
