чтобы найти 1 число, мы 1000 умножаем на 175%. но перед этим проценты превращаем в десятичную дробь: 175%=175/100=1,75

1 число → 1000×175%=1000×1,75=1750

1 число у нас 1750

чтобы найти 2 число, мы строим следующую пропорцию:

60/1080=100/х (х у нас 2 число)

60×х=1080×100

60х=108000

х=108000:60=1800

х=1800

2 число у нас 1800

сравниваем 1 и 2 число:

1750 < 1800

1 число < 2 число

видим, что 2 число больше, чем первое число.

ответ: 2 число число больше, чем 1 число.

Task. Read the text and fill in the table below with necessary information.


There are five main types of nutrients we need from our food. These are carbohydrates, proteins, fats, minerals and vitamins. A sixth important part of our diet is roughage or fibre. 

Carbohydrates 

Carbohydrates are mainly used by the body as fuel. Digestion breaks them into a simple sugar called glucose. This is carried in the blood to provide energy for all our body parts. 

Proteins 

Proteins perform many important jobs in the body. Your body needs them to grow, and to make repairs when it is damaged. 

Fats 

The body needs some fat to build its parts and keep them working properly. Fat can also be used as fuel, for energy. 

Fibre

Fibre does not provide nutrition, but it helps bulk up waste so that it passes easily through the body. People who do not consume enough roughage are more likely to suffer from constipation, which can sometimes lead to more serious diseases of the intestines. 

Minerals 

Minerals are simple substances such as calcium, iron and salt. You need to eat a lot of mineral-rich food when your body is growing. 

Vitamins 

Vitamins are special substances that your body needs in tiny amounts but cannot make itself.
