Answer 1

1)
28 * 3= 84 м - ткани ушло на шитье 28 блузок
320 - 84=236 м- остальная ткань
236 : 4=59 рубашек- сшили
ответ В-59
2)
648:3=216 кг-это одна из 3 частей всей моркови
216 :8=27 мешков- потребовалось

Answer 2

Calculation of the Number of Shirts Sewn

To calculate the number of shirts sewn, we need to determine the amount of fabric used for the blouses and the remaining fabric used for the shirts.

Given: - Total fabric brought to the studio: 320 meters - Fabric used for each blouse: 3 meters - Fabric used for each shirt: 4 meters

Let's calculate the number of blouses first: - Number of blouses = Total fabric used for blouses / Fabric used for each blouse - Number of blouses = 28 blouses

The total fabric used for blouses can be calculated as follows: - Total fabric used for blouses = Number of blouses * Fabric used for each blouse - Total fabric used for blouses = 28 blouses * 3 meters/blouse - Total fabric used for blouses = 84 meters

The remaining fabric can be calculated as follows: - Remaining fabric = Total fabric brought to the studio - Total fabric used for blouses - Remaining fabric = 320 meters - 84 meters - Remaining fabric = 236 meters

Now, let's calculate the number of shirts: - Number of shirts = Remaining fabric / Fabric used for each shirt - Number of shirts = 236 meters / 4 meters/shirt - Number of shirts = 59 shirts

Therefore, the number of shirts sewn is 59.

Calculation of the Number of Bags for Carrots

To calculate the number of bags required for the carrots, we need to determine the total weight of the carrots and the weight of each bag.

Given: - Total weight of carrots: 648 kg - Weight of each bag: 8 kg

Let's calculate the number of bags: - Number of bags = Total weight of carrots / Weight of each bag - Number of bags = 648 kg / 8 kg/bag - Number of bags = 81 bags

Therefore, the number of bags required for the carrots is 81.
