Сочинение на тему как я отдохнул летом с семьёй на языке

This summer has been interesting. the first month of rest was much like the previous summer holidays because i was staying in the city. however, the next two summer months were for me amazingly interesting - i spent them in the village with his aunt. it is with these days spent outside the city, i have linked the brightest events and lasting impressions of my summer.time passes slowly in the village, it is not so, as in metropolitan areas. it seems that a month has passed, whereas in fact - only a week. my morning usually begins with the help of my aunt in the garden. our village is far from the village, and the water from the tap is unheard of luxury. so i go to the well with two old iron buckets. the water is amazingly clear and very cold. i also help my aunt in the house, but at the first opportunity to run to play with friends.i have good friends in the village. we spend all our free time together. in the hottest hours, we were sitting on the bank of the river. after a swim, frolic with might and main, and look at the passing barges. once i flew from my aunt, because i did not come to dinner. and actually i do not want to have, because with a friend pasha we baked potatoes in the fire. it is such a pleasure - to shift from one hand to a hot potato, and then crush it and eat a piece. we agree that this is not a plate of cooked soup? and most importantly - how much romance and happiness in these summer days spent as though in another world! summer evenings i spent in this wooden hut. as a rule, after dinner, my aunt came to visit a girlfriend. sitting at a large round table, they drank tea. i hid a large stone oven, or saw the book, or "beat thumbs," as my grandmother used to say. and in truth, i kept a diary, and, like robinson crusoe on a desert island, counting the days until his return to the city.sometimes it occurs to me that the village - a remote island of the city, and the life on it is subject to a different rhythm. whether because of the proximity to nature, and perhaps simply because the big cities in the endless pursuit of technological advances come off quiet measured life. but be that as it may, i am a city person. so, my place there. and yet, each time leaving this quiet island of tranquility, i will 

Надо разложить число 90 на простые множители: 90=2*3*3*5, теперь надо определить все делители числа 90, путем перемножения простых множителей: 1,2,3,5,6,9,10,15,18,30,45,90, теперь из этих делителей, нужно выбрать пары взаимно простых чисел, т.е. тех, которые не имеют общих делителей: 1) 90=45*2 45=5*3*3; 2=2 2) 90=18*5 5=5; 18=3*3*2 3) 90=90*1 90=3*3*5*2; 1=1 4) 90=10*9 10=2*5; 9=3*3
