Answer 1

1 28м=2800 2800+80=2880
2 2880÷9=320 см за 1 костюм
320×60=19200 см понадобится для 60 костюмов

Answer 2

28 м 80 см = 2880 см
1) 2880:9=320 (см)- потребуется на один костюм.
2) 320×60=19200(см)- потребуется на 60 костюмов.
Ответ: 19200 см = 192м.

Answer 3

Solution:

To solve this problem, we can use the concept of proportions. We know that 28 meters and 80 centimeters of fabric are used to make 9 men's suits. We can use this information to find out how much fabric is needed for 60 suits.

Let's start by finding out how much fabric is needed for one suit and then use that to calculate the total fabric needed for 60 suits.

Calculations:

First, let's convert 80 centimeters to meters: - 80 centimeters = 0.8 meters

Now, we can find out how much fabric is needed for one suit: - Total fabric for 9 suits = 28 meters + 0.8 meters = 28.8 meters - Fabric for one suit = 28.8 meters / 9 = 3.2 meters per suit

Now, we can calculate the total fabric needed for 60 suits: - Fabric for 60 suits = 3.2 meters/suit * 60 suits = 192 meters

So, 192 meters of fabric will be needed to make 60 men's suits.

Answer:

The sewing workshop will need 192 meters of fabric to make 60 men's suits.
