Question

на 5 детских свитеров расходуют столько же шерстяной пряжи,сколько на 2 свитера для взрослых.сколько пряжи идёт на детский свитер,если на свитер для взрослых расходуют 500 г пряжи?

Answer 1

Если мы знаем сколько один взрослый свитер (500г) то надо узнать 2 взрослых свитера

1)500*2=1000(г)-2 взрослых свитера

Тоесть 1000грамм пряжи это 5 детских свитера. Теперь мы можем узнать сколько на один детский свитер надо пряжи

2)1000:5=200(г)

Ответ:200грамм

Answer 2

Calculation of Yarn for Children's Sweater

To determine how much yarn is required for a children's sweater, given that the same amount of yarn is used for 2 adult sweaters, we need to calculate the yarn requirement for the adult sweater first.

Let's assume that 500 grams of yarn is used for an adult sweater.

Now, we can calculate the yarn requirement for a children's sweater.

According to the given information, the amount of yarn used for 5 children's sweaters is the same as the amount used for 2 adult sweaters.

To find the amount of yarn used for a single children's sweater, we can set up a proportion:

5 children's sweaters = 2 adult sweaters

1 children's sweater = ? grams of yarn

Using cross-multiplication, we can solve for the unknown amount of yarn used for a children's sweater:

5 children's sweaters * 500 grams of yarn = 2 adult sweaters * ? grams of yarn

? grams of yarn = (5 children's sweaters * 500 grams of yarn) / 2 adult sweaters

Calculating this, we find that the amount of yarn used for a children's sweater is:

? grams of yarn = (5 * 500) / 2 = 1250 grams of yarn

Therefore, 1250 grams of yarn is required for a children's sweater if 500 grams of yarn is used for an adult sweater.

Please note that the above calculation is based on the assumption that the same amount of yarn is used for each sweater, and it may vary depending on the specific design and size of the sweaters.

I hope this helps! Let me know if you have any further questions.
