Answer 1

Ответ:24целых 80/100 метров

Пошаговое объяснение:переводим 20% в дробь(20/100) находим НОК (5,100)=100

2/5=40/100

24=23целых 100/100

40/100+20/100+23 ц.100/100. если сократить=24ц. 4/5

Answer 2

To find the answer to your question, let's break down the information given:

- 2/5 of the purchased fabric was used for making dresses. - 20% of the remaining fabric was used for making pants. - The rest, which is 24 meters, was used for making skirts.

To determine the total amount of fabric purchased, we need to find the amount of fabric used for dresses, pants, and skirts separately, and then add them together.

Calculation:

1. Dresses: 2/5 of the purchased fabric. 2. Pants: 20% of the remaining fabric after making dresses. 3. Skirts: The rest of the fabric, which is 24 meters.

Let's calculate each step:

1. Dresses: - The amount of fabric used for dresses is 2/5 of the total fabric purchased. - Let's assume the total fabric purchased is "x" meters. - The amount of fabric used for dresses is (2/5) * x meters.

2. Pants: - After making dresses, there is some fabric remaining. - The amount of fabric remaining is (3/5) * x meters (since 2/5 was used for dresses). - 20% of the remaining fabric is used for pants. - The amount of fabric used for pants is (20/100) * (3/5) * x meters.

3. Skirts: - After making dresses and pants, there is still 24 meters of fabric remaining. - The amount of fabric used for skirts is 24 meters.

Now, let's add up the fabric used for dresses, pants, and skirts to find the total amount of fabric purchased:

Total fabric purchased = Fabric used for dresses + Fabric used for pants + Fabric used for skirts

Total fabric purchased = (2/5) * x +
