Question

ПОМОГИТЕ!!!! Выпускаемая домом мод продукция содержит 25% костюмов, из них 20% детские костюмы. сколько детских костюмов сошьют за 15 дней 16 портных, если каждый портной шьёт по 7 изделий в день? составте схему можно и с Х

Answer 1

Дано: время--- 15 дней
портных ---- 16 чел.
в день шьет каждый ---- 7 изделий 
костюмов ---- 25 % всех изд.
детских ----- 20 % всех кост.
Найти:сколько детских?
Решение:
7 * 16 = 112 (шт.) ------- шьют изделий все портные в день
112 *15 = 1680 (шт.)---- сошьют изделий все портные за 15 дней.
1680 * 25% = 1680 * (25/100) = 420 (шт.) ---- сошьют костюмов
420 * 20% = 420 * (20/100) = 84 (шт.)  ---- сошьют детских костюмов
Ответ:84 детских костюма.

   Если обозначить через Х детские костюмы, а % перевести в десятичные дроби ( 25% = 25/100 = 0,25 ; 20% = 20/100 = 0,2 ) то Х = (7*16*15)*0,25*0,2 = 84 (шт.)

Answer 2

Calculating the Number of Children's Costumes

To calculate the number of children's costumes that will be sewn in 15 days by 16 tailors, we can use the following steps:

1. Calculate the total number of costumes produced in 15 days. 2. Determine the proportion of children's costumes in the total production. 3. Calculate the number of children's costumes based on this proportion.

Let's proceed with the calculations.

Step 1: Total Number of Costumes Produced

Given: - 16 tailors - Each tailor sews 7 items per day - Time: 15 days

The total number of costumes produced can be calculated as follows: Total number of costumes = Number of tailors * Number of items sewn per day * Number of days Total number of costumes = 16 * 7 * 15

Let's calculate the total number of costumes.

Step 2: Proportion of Children's Costumes

Given: - 25% of the produced costumes are children's costumes

To find the number of children's costumes, we need to determine the proportion of children's costumes in the total production.

Step 3: Calculating the Number of Children's Costumes

Using the proportion of children's costumes, we can calculate the number of children's costumes.

Let's proceed with the calculations.

Solution

1. Total number of costumes: Total number of costumes = 16 * 7 * 15 Total number of costumes = 1680

2. Proportion of children's costumes: 25% of 1680 = 0.25 * 1680 25% of 1680 = 420

3. Calculating the number of children's costumes: Number of children's costumes = 20% of total costumes Number of children's costumes = 0.20 * 420 Number of children's costumes = 84

Therefore, 84 children's costumes will be sewn in 15 days by 16 tailors.
