Answer 1

18*2=36 мотков пошло на пошив детских шарфов
36/12=3 мотка пряжи пошло на 1шапочку

Answer 2

Calculation of Yarn Balls for Scarves and Hats

To determine the number of yarn balls required for each hat, we need to find the ratio between the number of scarves and the number of hats.

Given that 18 scarves require the same amount of yarn as 12 hats, we can set up the following equation:

18 scarves = 12 hats

To find the number of yarn balls required for each hat, we need to divide the total number of yarn balls used for scarves by the number of hats:

Total yarn balls for scarves / Number of hats = Yarn balls per hat

Since each scarf requires 2 yarn balls, we can calculate the total number of yarn balls used for scarves:

Total yarn balls for scarves = 18 scarves * 2 yarn balls per scarf

Now, let's substitute the values into the equation:

Total yarn balls for scarves / 12 hats = Yarn balls per hat

18 scarves * 2 yarn balls per scarf / 12 hats = Yarn balls per hat

36 yarn balls / 12 hats = Yarn balls per hat

Each hat requires 3 yarn balls.

Therefore, 3 yarn balls were used for each hat.
