Question

Во вторник в ателье сшили 11 одинаковых курток, а в среду - 13 таких же курток. Всего на них израсходовали 72 м ткани. Сколько метров ткани израсходовали в каждый из них дней ?

Answer 1

72:(11+13)=72:24=3 м пошло на 1 куртку
3*11= 33 м - в первый день
3*13=39 м - во второй день

Answer 2

Calculation of Fabric Used for Jackets

To calculate the amount of fabric used for each day, we need to determine the fabric used per jacket on each day.

On Tuesday, 11 identical jackets were made, and a total of 72 meters of fabric was used. Therefore, to find the amount of fabric used per jacket on Tuesday, we divide the total fabric used by the number of jackets:

Fabric used per jacket on Tuesday = Total fabric used / Number of jackets on Tuesday

Using the given information: - Number of jackets on Tuesday = 11 - Total fabric used = 72 meters

Substituting these values into the formula, we can calculate the fabric used per jacket on Tuesday:

Fabric used per jacket on Tuesday = 72 meters / 11 jackets

Calculating this, we find that the fabric used per jacket on Tuesday is approximately 6.55 meters.

On Wednesday, 13 identical jackets were made, and a total of 72 meters of fabric was used. To find the amount of fabric used per jacket on Wednesday, we use the same formula:

Fabric used per jacket on Wednesday = Total fabric used / Number of jackets on Wednesday

Using the given information: - Number of jackets on Wednesday = 13 - Total fabric used = 72 meters

Substituting these values into the formula, we can calculate the fabric used per jacket on Wednesday:

Fabric used per jacket on Wednesday = 72 meters / 13 jackets

Calculating this, we find that the fabric used per jacket on Wednesday is approximately 5.54 meters.

Therefore, the amount of fabric used in each of the two days is approximately: - Tuesday: 6.55 meters per jacket - Wednesday: 5.54 meters per jacket

Please note that these calculations are approximate and may vary slightly depending on the rounding method used.
