Ответ:

3,5

Объяснение:

в начале мы 6/c отнимаем от 3/4c

находим общий знаменатель (общ. знаменатель 4c)

т.е 24/4c=6/c

24/4c - 3/4c = 21/4c

вместо C подставляем 1,5

21/ 6=3,5

Endangered Species Watch
The Orangutan is a great ape which is found on the islands of Borneo and Sumatra in South East Asia. These gentle great apes are very intelligent and, like humans, they have the ability to think and learn. They are the largest tree-living mammal, with longer arms than other great apes such as gorillas and chimpanzees.
Orangutans are an endangered species because of illegal hunting, loss of their habitat and being kidnapped from the wild and sold as pets. In fact, it is possible that orangutans living in the wild may become extinct very soon. The loss of their habitat has occurred for various reasons. As the populations of countries in South East Asia have grown, so has the need for land and food. The rainforests have been cut down to clear land for housing and agriculture. In particular, whole sections of rainforest have been cleared to plant palm trees which produce palm oil. As a result, the orangutans have no home. In addition, natural disasters such as flooding and forest fires have also contributed to the destruction of the rainforests.
The survival of orangutans depends mainly on the efforts of various conservation organisations which are working hard to protect them. For example, Camp Leakey is a research station in the Tanjung Puting National Park in Borneo; here orangutans are studied, cared for and prepared for life in the wild. Despite the work of organisations such as these, orangutans are still threatened; if we want to save these magnificent creatures from extinction, more needs to be done to protect their habitats.
