Question

В куске 25м ткани.Хватит ли этой ткани,что бы сшить 6 платьев,расходуя на каждое платье по 3м ткани?Сколько метров ткани останется ,если расходовать на каждое по 4м?по5м?

Answer 1

Найдем расходуемое количество ткани для пошива шести платьев
6*3=18 м - будет израсходовано ткани.
найдем остатки ткани если расходовать по 4 метра
25-6*4=25-24=1 м - ткани останется
найдем остатки ткани если расходовать по 5 метров
25-6*5=25-30=-5м - не хватит для пошива шести платьев

Answer 2

Calculation of Fabric Required

To determine if 25 meters of fabric is enough to sew 6 dresses, with each dress requiring 3 meters of fabric, we can calculate the total fabric required and compare it to the available fabric.

The total fabric required for 6 dresses, with each dress requiring 3 meters of fabric, can be calculated as follows:

Total fabric required = Number of dresses * Fabric required per dress

Total fabric required = 6 dresses * 3 meters/dress

Total fabric required = 18 meters

Therefore, if each dress requires 3 meters of fabric, a total of 18 meters of fabric would be needed to sew 6 dresses.

Calculation of Remaining Fabric

To determine how much fabric would be left if each dress requires 4 meters or 5 meters of fabric, we can subtract the fabric required for each dress from the available fabric.

1. If each dress requires 4 meters of fabric: - Total fabric required = 6 dresses * 4 meters/dress = 24 meters - Remaining fabric = Available fabric - Total fabric required - Remaining fabric = 25 meters - 24 meters = 1 meter

2. If each dress requires 5 meters of fabric: - Total fabric required = 6 dresses * 5 meters/dress = 30 meters - Remaining fabric = Available fabric - Total fabric required - Remaining fabric = 25 meters - 30 meters = -5 meters

Based on these calculations: - If each dress requires 4 meters of fabric, there would be 1 meter of fabric remaining. - If each dress requires 5 meters of fabric, there would be a deficit of 5 meters.

Please note that if each dress requires more fabric than the available 25 meters, there would not be enough fabric to sew all the dresses.
