2) \: \frac{a}{c} + \frac{4}{c} = \frac{a + 4}{c}. \\ \\ 4) \: \frac{1}{c} + \frac{3}{2c} = \frac{2 + 3}{2c} = \frac{5}{2c} . \\ \\ 6) \frac{2a}{3c} + \frac{a}{6c} = \frac{4a + a}{6c} = \frac{5a}{6c} .

Нужно сделать максимально краткий пересказ этих текстов
A) Sledding in Russia
This winter why not escape to Yakutia in Russia, where you can have the experience of a lifetime driving a reindeer sled through the heart of Siberia? Wrap up in warm furs and travel through the valleys of the Lena River and over the frozen landscape, just like the native Yakutian people, who have travelled this way for centuries. You can spend your evenings in traditional Russian family homes, enjoy home-cooked meals, and learn about the rich culture of these people. During your trip, you will have the chance to see all sorts of amazing wildlife including wolves, foxes and elk, and you will even be able to ride the famous Yakut horses.

B) Camel Riding in Marocco
See all of southern Morocco on a camel! Take your time and enjoy a relaxing journey from Marrakech with historic sites across the desert to the Dades Gorge. Spend a night in a nomad's tent, visit traditional Berber villages and Kasbahs1, see the Atlas Mountains and relax on the beautiful beaches at Essaouira. You will see so much more than sand because Morocco has many varied landscapes. The perfect escape from a busy life!

C) Wagon Travel in Wyoming
Have you ever wondered what it was like back in the Wild West? Well, now you can find out for yourself with a holiday that offers the unique opportunity to see how life might have been over 150 years ago. You will travel in a convoy of covered wagons through the unspoilt countryside of Yellowstone National Park and through Wyoming, and enjoy the majestic views all around. Stopping at a different camp each day, there will be plenty of opportunities to go on nature hikes, go swimming, canoeing, horse riding, or just relax. You can spend your evenings cooking on an open fire and singing cowboy songs around the campfire.

D) Ice Diving in the Arctic
In the icy waters of the Arctic Ocean, you will see a strange but unique world that very few humans get the chance to visit. The Arctic is one of the last places on earth that remains a mystery and a challenge.
Not many people are brave enough to explore the region and even fewer are brave enough to explore it from twenty feet beneath the ice! If the diving experience is not enough, you can also enjoy the scenery and wildlife above the ocean on foot or on snowmobiles. One thing is for sure; no one else will have holiday snaps like yours!
