Question

Сделать краткую запись к задаче и решить ее? На 5 одинаковых шапочек израсходовали 15 мотков пряжи.Сколько мотков пряжи пошло на изготовление двух шапочек;четырех шапочек? Сколько мотков пряжи нужно, чтобы изготовить 6 шапочек; 7 шапочек; 9 шапочек?

Answer 1

1) 15:5=3(м) - израсходовали на 1 шапку.
2) 3·2=6(м) для 2 шапок
3) 3·4=12(м) для 4 шапок
4) 3·6=18(м) для 6 шапок
5) 3·7=21(м) для 7 шапок
6) 3·9=27(м) для 9 шапок
Ответ: 6 матков пряжи, 12 матков, 18 матков, 21 матков, 27 матков.

Answer 2

15:5=3(мотка пряжи на одну Шапочку)
3*2=6(мотков на две шапочки)
3*4=12(мотков на четыре шапочки)
3*6=18(мотков на шесть шапочек)
3*7=21(моток на семь шапочек)
3*9=27(мотков на девять шапочек)

Answer 3

Task:

На 5 одинаковых шапочек израсходовали 15 мотков пряжи. Сколько мотков пряжи пошло на изготовление двух шапочек? Четырех шапочек? Сколько мотков пряжи нужно, чтобы изготовить 6 шапочек? 7 шапочек? 9 шапочек?

Solution:

To find out how many balls of yarn were used to make a certain number of hats, we can use the concept of ratios.

Let's first find the ratio of hats to balls of yarn. We know that 5 hats were made using 15 balls of yarn. So the ratio of hats to balls of yarn is 5:15.

To find out how many balls of yarn were used to make a different number of hats, we can use this ratio.

1. Two hats: To find out how many balls of yarn were used to make two hats, we need to find the equivalent ratio. Since the ratio of hats to balls of yarn is 5:15, we can set up a proportion:

5 hats / 15 balls of yarn = 2 hats / x balls of yarn

Solving for x, we get:

x = (2 * 15) / 5 = 6

Therefore, 6 balls of yarn were used to make two hats.

2. Four hats: Using the same approach, we can find out how many balls of yarn were used to make four hats:

5 hats / 15 balls of yarn = 4 hats / x balls of yarn

Solving for x, we get:

x = (4 * 15) / 5 = 12

Therefore, 12 balls of yarn were used to make four hats.

3. Six hats: Using the same approach, we can find out how many balls of yarn were used to make six hats:

5 hats / 15 balls of yarn = 6 hats / x balls of yarn

Solving for x, we get:

x = (6 * 15) / 5 = 18

Therefore, 18 balls of yarn were used to make six hats.

4. Seven hats: Using the same approach, we can find out how many balls of yarn were used to make seven hats:

5 hats / 15 balls of yarn = 7 hats / x balls of yarn

Solving for x, we get:

x = (7 * 15) / 5 = 21

Therefore, 21 balls of yarn were used to make seven hats.

5. Nine hats: Using the same approach, we can find out how many balls of yarn were used to make nine hats:

5 hats / 15 balls of yarn = 9 hats / x balls of yarn

Solving for x, we get:

x = (9 * 15) / 5 = 27

Therefore, 27 balls of yarn were used to make nine hats.

In summary: - Two hats required 6 balls of yarn. - Four hats required 12 balls of yarn. - Six hats required 18 balls of yarn. - Seven hats required 21 balls of yarn. - Nine hats required 27 balls of yarn.
