After my hard and busy school year my summer holidays began. I felt happy and began to plan a lot of wonderful things to do during my summer vacation.
I was dreaming about far South countries I always wanted to visit but I had to go to the Azove seaside with my relatives. The water was very warm there because you know Azove Sea isn’t deep. What I liked there - a lot of different kinds of entertainment there: "water mountains", water scooters and discos.
There was nothing to do all day except lying in the sun and getting a wonderful tan. I was playing with my little sister on the sand and in the waves teaching her to swim. Later I returned to Kherson and spent some time in town going out with my friends, reading, listening to music, watching TV, playing computer games. After that I went to the sports camp where I spent seven days.
It was very useful experience because I had to get up very early, to train a lot, and to rest very little. But it made me stronger and healthier.
I was very happy to return home and I spent several days in my summer cottage, I helped my grandpa to dig the garden, to water plants, and to gather fruit and vegetables. I was fishing with my grandpa and we were cooking fish together. Only insects were spoiling my good mood. I enjoyed floating by boat, swimming in the river and helping my grandparents.
During my summer holidays I made many new friends, read a lot of interesting books, got to know a lot of useful things. Now I feel ready to get back to school.
Пошаговое объяснение:
"Лекарство нужно пить 3 раза по 0,5 гр в день в течение 7 дней".
Для начала найдем, сколько должен больной принимать лекарство больной в день:
1) 0,5 гр * 3 = 1,5 гр - в день.
То есть, больной должен принимать 1,5 грамма лекарства в течение семи дней. Узнаем, сколько граммов лекарства будет использовано за неделю лечения:
2) 1,5 гр * 7 = 10,5 граммов.
В условии задачи сказано, что в одной упаковке 10 таблеток, и каждая таблетка весит по 0,25 грамма.
Находим общий вес таблеток:
3) 0,25 гр * 10 = 2,5 гр - общий вес таблеток в упаковке (при умножении дес.дроби на 10 запятая вправо на один знак).
Ну а теперь можем найти количество упаковок, разделив 10,5 грамм на 2,5
4) 10,5 : 2,5 = 105 : 25 = 4,2 ≈ 4 ≈ 5 (вспомни правила деления дес.дробей)
А вообще, тут ответы могут быть разные: кто-то 4,2 округлит до 5, а кто-то до 4. Тут уже думай сам.
Задача решена.

I am happy to meet my friends and teachers.
