Question

На пошив 25 наволочек израсходовали ткани на 32 метра 40 сантиметров больше чем в 13 таких же наволочек Хватит ли 110 метров ткани для пошива 40 таких же наволочек Сколько метров ткани нужно для пошива 41 наволочки

Answer 1

1)25-13=12(н) - на них потратили 32м 40см ткани
2)3240:12 =270(см) - на 1 наволочку
3) 270*40 = 10800(см) - надо
110 м =11000 см
10800 см =108 м
Ответ: этого нам хватит
4) 270*41 =11070(см) на 41 наволоку
11070 см =110 м 70 см
Ответ: на пошив 41 наволочки понадобится 110 м 70 см ткани.

Answer 2

Calculation of Fabric Required for 25 Pillowcases

To determine the amount of fabric required for 25 pillowcases, we need to find the difference in fabric used between 32 meters 40 centimeters and 13 pillowcases.

Let's calculate the fabric used for 13 pillowcases first: - Fabric used for 13 pillowcases = 32 meters 40 centimeters

Now, we need to find the fabric used for 1 pillowcase: - Fabric used for 1 pillowcase = (Fabric used for 13 pillowcases) / 13

Next, we can calculate the fabric required for 25 pillowcases: - Fabric required for 25 pillowcases = (Fabric used for 1 pillowcase) * 25

Let's calculate the fabric required for 25 pillowcases using the given information: - Fabric used for 13 pillowcases = 32 meters 40 centimeters - Fabric used for 1 pillowcase = (32 meters 40 centimeters) / 13 - Fabric required for 25 pillowcases = (Fabric used for 1 pillowcase) * 25

To calculate the fabric required for 25 pillowcases, we need to convert the measurements to the same unit. Let's convert centimeters to meters: - 40 centimeters = 0.4 meters

Now, we can calculate the fabric required for 25 pillowcases: - Fabric used for 1 pillowcase = (32 meters + 0.4 meters) / 13 - Fabric required for 25 pillowcases = (Fabric used for 1 pillowcase) * 25

Let's calculate the fabric required for 25 pillowcases: - Fabric used for 1 pillowcase = (32 + 0.4) / 13 - Fabric required for 25 pillowcases = (Fabric used for 1 pillowcase) * 25
