Calculating the Number of 200g Jars Required for 3kg of Jam

To calculate the number of 200g jars required for 3kg of jam, we can use the following steps based on the provided search snippets:

1. Convert 3kg to grams: - 3kg is equal to 3000g.

2. Calculate the number of 400g jars: - Given that there are 4 jars of 400g each, the total amount of jam in these jars is 4 * 400g = 1600g.

3. Calculate the remaining amount of jam: - Subtract the total amount of jam in the 400g jars from the total amount of jam: 3000g - 1600g = 1400g.

4. Calculate the number of 200g jars: - Divide the remaining amount of jam (1400g) by the capacity of each 200g jar: 1400g ÷ 200g = 7.

Therefore, the number of 200g jars required for 3kg of jam is 7.

Based on the provided search snippets, the calculation for the number of 200g jars required for 3kg of jam is confirmed to be 7.
