Question

В ателье привезли 420 м льняной ткани, а ткани из хлопка в 3раза меньше.Из 1/8 части всей ткани пошили детские платья.Сколько метров ткани использовалось для пошива детских платьев?

Answer 1

Ответ:

420 м -льняная ткань

а ткани из хлопка в три раза меньше .значит 420 м÷3=140 м

140 м -хлопковая ткань

420 м+140 м=560 м(хлопковая и льняная ткань вместе )

на пошив детских платьев ушла 1/8 всей ткани .значит 560 м÷8=70 м

Ответ:70 м использовалось для пошива детских платьев

Answer 2

1) 420÷3=140 (м) хлопковой ткани
2) 420+150=560 (м) всего
3)560÷8×1=70 (м)
Ответ: 70 метров ткани использовали для пошива детских платьев

Answer 3

Calculation of Fabric Used for Children's Dresses

To calculate the amount of fabric used for the children's dresses, we need to consider the total amount of fabric brought to the studio and the ratio of linen fabric to cotton fabric.

Given: - 420 meters of linen fabric - Cotton fabric is 3 times less than linen fabric

To find the amount of fabric used for the children's dresses, we need to determine the fraction of the total fabric that was used for the dresses.

Let's calculate the amount of cotton fabric first.

Step 1: Calculate the amount of cotton fabric. Since the cotton fabric is 3 times less than the linen fabric, we can divide the amount of linen fabric by 3 to find the amount of cotton fabric.

Amount of cotton fabric = 420 meters / 3 = 140 meters

Step 2: Calculate the total amount of fabric. To find the total amount of fabric, we add the amount of linen fabric and the amount of cotton fabric.

Total amount of fabric = 420 meters + 140 meters = 560 meters

Step 3: Calculate the fraction of fabric used for the children's dresses. The problem states that 1/8 of the total fabric was used for the children's dresses.

Fraction of fabric used for children's dresses = 1/8

Step 4: Calculate the amount of fabric used for the children's dresses. To find the amount of fabric used for the children's dresses, we multiply the total amount of fabric by the fraction used for the dresses.

Amount of fabric used for children's dresses = Total amount of fabric * Fraction of fabric used for children's dresses

Amount of fabric used for children's dresses = 560 meters * (1/8)

Amount of fabric used for children's dresses = 70 meters

Therefore, 70 meters of fabric were used for the children's dresses.
