2

1 - 1/6 = 5/6 - осталось прочитать после первого дня
5/6 * 4/10 = 1/3 - прочитано во второй день
1/6 меньше 1/3 в 2 раза
В 2 раза часть прочитанной книги за первый день меньше чем за второй день.

У меня проблемы с русским языком. Точки запятые надо проверить.)

Vladislav4uk: Спасибо

АнтонНовиков: Больше не чего не надо ?

It is very cold today. We are in the house. We are watching a film. It is about a mouse. Its name is Stuart Little. The film is very interesting. But, when I see a mouse, I am very hungry.

So I say:

"Let's watch another film!" "What film?" asks Blackie.

"Another film. Not about mice," I say.

"OK," says Blackie. He takes another film and we watch it. It is about a clown fish. Its name is Nemo. The film is very interesting. But, when I see a fish, I am hungry. So I say:

"Let's watch another film."

"What film?" asks Blackie.

"Another film. Not about fish," I say.

Blackie takes another film and we watch it. It is about a bird. Its name is Valiant. The film is very interesting. But, when I see a bird, I am hungry.

"Let's watch another film!" I say.

"Again?" cries Blackie. He is very angry.

"Oh Blackie," says Pinky. "I think, Reddy is very hungry. Let's have lunch. And then we can watch a film."

So we have lunch. Now I am not hungry and I can watch films about mice, fish or birds.

"Thank you, Pinky," I say. "You are so clever."
