Answer 1

1) 1кг400г=1400 г

2) 1400:2=700 г - весит одна часть (ягод) (сахара)

3) 2+3=5 частей в варенье

4) 700*5=3500 г - получится варенья

Answer 2

Calculating the Amount of Jam

To calculate the amount of jam that will be produced, we can use the given ratio of 2 parts berries to 3 parts sugar. If we start with 1.4 kg of berries, we can determine the amount of jam that will be produced.

First, we need to calculate the total amount of the mixture (berries + sugar) and then find the proportion of berries and sugar in the mixture.

Calculations

Using the given ratio of 2 parts berries to 3 parts sugar, we can calculate the total amount of the mixture and then find the amount of jam produced.

1. Total Mixture Weight: - Berries: 1.4 kg - Sugar: (2/3) * 1.4 kg = 0.933 kg

2. Total Mixture Weight: - Berries: 1.4 kg - Sugar: 0.933 kg - Total: 1.4 kg + 0.933 kg = 2.333 kg

3. Proportion of Berries in the Mixture: - Berries: 1.4 kg / 2.333 kg = 0.6 - Sugar: 0.933 kg / 2.333 kg = 0.4

Conclusion

If we start with 1.4 kg of berries and use a ratio of 2 parts berries to 3 parts sugar, we will end up with approximately 2.333 kg of jam.
