Question

У 840 кг готової ягідної карамелі 1\7 всієї маси становлять ягоди, 1\4-молока, а решту -цукор. Скільки кілограмів цукру використали для приготування карамелі?

Answer 1

1) 840/7 = 120( кг) - ягоди
2) 840/4 = 210 (кг) - молоко
3) 120+210 = 330 (кг) - ягоди та молоко
4) 840-330 = 510 (кг) - цукор

Відповідь: 510 кг цукру використали для приготування карамелі

Answer 2

Calculation of Sugar Used in Caramel Preparation

To calculate the amount of sugar used in the preparation of the caramel, we need to determine the proportion of sugar in the total mass of the caramel. According to the given information, 1/7 of the total mass consists of berries, 1/4 consists of milk, and the rest is sugar.

Let's assume the total mass of the caramel is 840 kg.

To find the amount of sugar used, we need to subtract the combined mass of berries and milk from the total mass and convert it to kilograms.

Calculation Steps:

1. Calculate the mass of berries: - 1/7 of the total mass is berries. - Mass of berries = (1/7) * 840 kg

2. Calculate the mass of milk: - 1/4 of the total mass is milk. - Mass of milk = (1/4) * 840 kg

3. Calculate the mass of sugar: - Subtract the combined mass of berries and milk from the total mass to find the mass of sugar. - Mass of sugar = Total mass - (Mass of berries + Mass of milk)

Let's calculate the values:

1. Mass of berries: - Mass of berries = (1/7) * 840 kg - Mass of berries = 120 kg

2. Mass of milk: - Mass of milk = (1/4) * 840 kg - Mass of milk = 210 kg

3. Mass of sugar: - Mass of sugar = 840 kg - (120 kg + 210 kg) - Mass of sugar = 840 kg - 330 kg - Mass of sugar = 510 kg

Therefore, 510 kilograms of sugar were used in the preparation of the caramel.

Please note that the calculations are based on the given information and assumptions made.
