Пусть 1 отрезок это 4х, тогда 2 отрезок 2х, а 3 отрезок х.
4х+2х+1х=7
7х=7
х=7:7
х=1
следовательно 1 отрезок равен 4, второй 2, третий 1

Bats
Bats are strange creatures: they have legs and feet but they cannot walk. So, they fly like birds and they are the only animals that can fly.Bats are most common in the tropics, where they can find food all the year round. Most bats are brownish in colour, but others are blackish, orange, grey, greyish green, greenish white, white, yellowish, and some are even spotted.
There are fruit-eating bats and insect-eating bats. There are also bats that catch and eat small fish. And there are bats that feed on blood.
Vampire bats are the only animals that feed on blood. These small tailless creatures live in Central and South America. With their two sharp upper teeth vampire bats make a small hole in the skin of another animal and suck blood from it. They sometimes bite human beings, too, but it happens very seldom. The wound they give their victims heals quickly, but these bats may carry rabies, that is why people are afraid of them.
Bats are usually active at night, when most people are asleep. In the daytime they hang close together in their attics, caves, or other dark places where they make their homes.
Bats hang upside down when they are resting. Only when evening comes do they begin to move. They go out of the hole into the night above to search for food. In the morning they come home from their night of work to sleep until the next night.
Bats have very few enemies. Some hawks, owls, and snakes can catch them, but it isn’t an easy thing for them.
Bats live as long as 10 years, some species live longer. Many strange and false legends have been told about bats. In Western countries people fear them and think that they bring bad luck. In China and Japan bats are symbols of good luck, happiness, and long life.
