Question

На 2 вязаные шапочки и 7 шарфов пошло 1 кг 800 г шерстяной пряжи.На шапочку и шарф расходовали пряжи поровну.Сколько граммов пряжи пошло отдельно на шапочки и сколько на шарфы?

Answer 1

Отдели 1кг 780 г и 659 г

Answer 2

1 кг 800 г = 1800 г
2+7=9 всего связанных предметов1800:9=200 (г) нужно на один предмет (хоть на шапочку, хоть на шарф)
а вот дальше вопрос не очень понятен "Сколько граммов пряжи пошло отдельно на шапочкУ и сколько на шарфЫ? "
если предположить, что в вопросе на шапочкИ и шарфы, то
200*2=400 (г) на две шапочки200*7=1400(г) на 7 шарфов.

Answer 3

Calculation of Yarn Usage for Hats and Scarves

To calculate the amount of yarn used for hats and scarves, we need to consider the following information:

- 2 hats and 7 scarves were made. - The total amount of yarn used was 1 kg 800 g.

Let's calculate the amount of yarn used separately for hats and scarves.

Yarn Usage for Hats

Since the yarn was used equally for each hat, we can divide the total amount of yarn by the number of hats to find the amount used for each hat.

Total amount of yarn used = 1 kg 800 g

Number of hats = 2

Amount of yarn used for each hat = Total amount of yarn used / Number of hats

Amount of yarn used for each hat = 1 kg 800 g / 2 = 900 g

Therefore, 900 grams of yarn were used for each hat.

Yarn Usage for Scarves

To calculate the amount of yarn used for scarves, we need to subtract the amount of yarn used for hats from the total amount of yarn.

Total amount of yarn used = 1 kg 800 g

Amount of yarn used for hats = 900 g (per hat) * 2 (number of hats) = 1800 g

Amount of yarn used for scarves = Total amount of yarn used - Amount of yarn used for hats

Amount of yarn used for scarves = 1 kg 800 g - 1800 g = 0 g

Therefore, no yarn was used for the scarves.

To summarize:

- 900 grams of yarn were used for each hat. - No yarn was used for the scarves.

Please note that the calculations are based on the provided information and assume that the yarn was used evenly for each hat and scarf.
