Ответ:

За 12 часов

Пошаговое объяснение:

8 рабочих - 24 часа

12 рабочих - х часов

Обратная пропорция (чем больше рабочих, тем меньше время, за которое будет выполнена работа)

8:12 = х:24

х=(8*24):12

х=12 (час) - за это время выполнят работу 12 рабочих

проверить текст на ошибки. Once upon a time some young man was sitting on sand and he was looking at the Pacific Ocean. He knew a lot of legends connected with this place. The first legend told him his grandmother, when he was 7 years old. The legend begins with a story of a little boy who wanted be a sailor. He knows a lot of the Pacific Ocean. But nobody believe in his stories about oceans, enormous creatures and extremely beautiful mermaids. Everyone blame on him because of his "lies". But in fact that weren't lies in his stories. Then my grandma said that that guy was swimming on a sheep. But that sheep was very unusual. It was made of iron! When many people murmured about the iron sheep and laughing to this impossible thing. His parents said: This was the last straw of your lies! After he was kicked out by his parents. He decided to walk around to the east coast of Canada. Some time later there were children who play together by the Pacific Ocean. For a while these children was seeing a big ship made with iron. They go home and told it to their parents. But one of the children did not come back home. He was into ships and it was very interesting to him to see close the iron ship. When everyone was going home he lifted out to this ship and nobody see him for a while. Whatever happened but he wants to climb up there and see something strange and extraordinary. He returns for a while, he was calm and say nothing about his disappearence.
