Question

На швейной фабрике было 1000м бельевой ткани.На пошив простыни идет 4м ткани а на пошив пододеяльников в 2раза больше.Было сшито 90простыней а пододеяльников в 3раза меньше Сколько метров ткани осталось?

Answer 1

Всего было    -   1000 м  
Всего израсходовали    - ? м 
В том числе :
Простыни  -  90 шт. по 4 м
Пододеяльники  - ? шт. (в  3 раза < )   по  ? м   (в  2 раза  > )
Всего  осталось   - ?  м 

1)  4 *2 = 8 (м) ткани израсходовали на пошив 1-го пододеяльника
2)  90 : 3 = 30 (пододеяльников) было сшито
3)  90 * 4 = 360 (м) ткани израсходовали   на пошив  90 простыней
4)  30  * 8 = 240 (м) ткани израсходовали на пошив  30 пододеяльников
5)  360 + 240 = 600(м) ткани израсходовали всего
6)1000 - 600 = 400 (м) ткани осталось

Ответ:  400  м  ткани осталось.

Answer 2

Calculating Remaining Fabric

To calculate the remaining fabric, we can follow these steps:

1. Calculate the total fabric used for making sheets and duvet covers. 2. Subtract the total fabric used from the initial amount of fabric to find the remaining fabric.

Let's proceed with the calculations.

Step 1: Calculate Total Fabric Used

- Fabric used for making sheets: - Number of sheets = 90 - Fabric required for each sheet = 4 meters - Total fabric used for sheets = 90 sheets * 4 meters/sheet

- Fabric used for making duvet covers: - Number of duvet covers = 90 sheets / 3 (as duvet covers are made in 3 times fewer quantities than sheets) - Fabric required for each duvet cover = 4 meters * 2 (as duvet covers require twice the fabric of a sheet) - Total fabric used for duvet covers = Number of duvet covers * Fabric required for each duvet cover

Step 2: Calculate Remaining Fabric

- Initial amount of fabric: 1000 meters - Total fabric used: Sum of fabric used for sheets and duvet covers

Now, let's calculate the remaining fabric.

Calculations

- Total fabric used for sheets = 90 sheets * 4 meters/sheet = 360 meters - Total fabric used for duvet covers = (90 sheets / 3) * (4 meters * 2) = 90 duvet covers * 8 meters/duvet cover = 720 meters - Total fabric used = 360 meters + 720 meters = 1080 meters - Remaining fabric = Initial amount of fabric - Total fabric used

Result

The remaining fabric is 1000 meters - 1080 meters = -80 meters.

It seems that the total fabric used exceeds the initial amount of fabric, resulting in a negative value for the remaining fabric. This suggests that there may be an error in the provided information or calculations.
