Question

Реши задачу двумя способами.... Одна бригада в день шьёт 18 пододеяльников, а другая – 24. Сколько пододеяльников сошьют обе бригады за 5 дней? Реши двумя способами.

Answer 1

Ответ:1:

1)18•5=90(пододеяльников)-1 бригада

2)24•5=120(подод.)-2 бригада

3)120+90=210(подод.)- всего за 5 дней обе бригады

2 способ:

(18+24)•5=210(подод.)-всего

Пошаговое объяснение:

Answer 2

Первый способ:18+24=42(п)-сделала обе бригады вместе
42*5=210(п)-сделала обе бригады за 5 дней
Второй способ:18*5=90(п)-сделала первая бригада за 5 дней
24*5=120(п)-сделала другая бригада за 5 дней
120+90=210(п)-сделала обе бригады за 5 дней
Вот и все

Answer 3

To solve the problem of how many duvet covers both teams will sew in 5 days, we can use two different methods: the direct method and the multiplication method.

Direct Method:

In the direct method, we calculate the total number of duvet covers sewn by each team in one day and then add them together to find the total number of duvet covers sewn by both teams in one day. Finally, we multiply this total by 5 to find the total number of duvet covers sewn by both teams in 5 days.

Let's calculate it step by step:

1. Calculate the number of duvet covers sewn by the first team in one day: - The first team sews 18 duvet covers in one day.

2. Calculate the number of duvet covers sewn by the second team in one day: - The second team sews 24 duvet covers in one day.

3. Calculate the total number of duvet covers sewn by both teams in one day: - Add the number of duvet covers sewn by the first team (18) to the number of duvet covers sewn by the second team (24): - 18 + 24 = 42 duvet covers sewn by both teams in one day.

4. Calculate the total number of duvet covers sewn by both teams in 5 days: - Multiply the total number of duvet covers sewn by both teams in one day (42) by the number of days (5): - 42 * 5 = 210 duvet covers sewn by both teams in 5 days.

Therefore, both teams will sew 210 duvet covers in 5 days using the direct method.

Multiplication Method:

In the multiplication method, we multiply the number of duvet covers sewn by each team in one day by the number of days to find the total number of duvet covers sewn by both teams in 5 days.

Let's calculate it step by step:

1. Calculate the number of duvet covers sewn by the first team in 5 days: - The first team sews 18 duvet covers in one day. - Multiply the number of duvet covers sewn by the first team in one day (18) by the number of days (5): - 18 * 5 = 90 duvet covers sewn by the first team in 5 days.

2. Calculate the number of duvet covers sewn by the second team in 5 days: - The second team sews 24 duvet covers in one day. - Multiply the number of duvet covers sewn by the second team in one day (24) by the number of days (5): - 24 * 5 = 120 duvet covers sewn by the second team in 5 days.

3. Calculate the total number of duvet covers sewn by both teams in 5 days: - Add the number of duvet covers sewn by the first team (90) to the number of duvet covers sewn by the second team (120): - 90 + 120 = 210 duvet covers sewn by both teams in 5 days.

Therefore, both teams will sew 210 duvet covers in 5 days using the multiplication method.

In conclusion, both methods yield the same result: both teams will sew 210 duvet covers in 5 days.
