Решение задачи:
Переведем центнеры в килограммы.
1 ц. = 1 * 100 = 100 килограмм.
1. Вычислим сколько школьных тетрадей можно сделать из 100 килограммов макулатуры.
100 * 25 = 2500 тетрадей.
2. Узнаем какое количество тетрадей можно сделать с 1 тонны макулатуры. Переведем тонны в килограммы.
1 т. = 1 * 1000 = 1000 килограмм.÷
1000 * 25 = 25 000 тетрадей.
ответ: Из ста килограммов макулатуры можно изготовить две тысячи пятьсот тетрадей, а из одной тонны макулатуры можно изготовить двадцать пять тысяч тетрадей
There lived an astronomer who was very much involved in his observations.
He often used to look up at the sky at night and start observing the stars.
Once, as he walked looking up at the stars, his leg slipped and he fell into a ditch. He started shouting.
A passer-by, who heard his shouts, helped him out of the ditch and asked, "How did you fall into this ditch?" The astronomer replied, “I was so engrossed in my observations that I did not notice the ditch".
The passer-by asked, "How do you expect to discover things when you fail to take note of things under your nose?" The astronomer walked away with a sad face.
