0,8 - x = 0,72 : 1,5
0,8 - x = 0,48
x = 0,8 - 0,48 = 0,32
Znanija000: 1) 0,72 : (0,8 - х) = 1,5

0,8 - х = 0,72 : 1,5

0,8 - х = 0,48

х = 0,48 - 0,8

х = 0,32
artemmedvedev2: неправильно 0.72÷1.5=0.52!
artemmedvedev2: ой правильно

Пожалуйста, Сократите текст. Чтобы было понятно о чем сказано в тексте!!!

Wendy wanted to know more about this interesting boy.

“How old are you?" asked Wendy.

“I don't know," said Peter. “But I am quite young. I ran away the day l was born. I didn’t want to
grow up, you see.”

Wendy was very surprised.

“But where did you go?” asked Wendy.

“I went to live with the fairies for a long time,” said Peter.

Wendy asked lots of questions about fairies and Peter told her about the beginning of the fairies.

“Fairies come from babies' laughs," he told her. “But children don't believe In fairies any more. 1
They know too much."

He looked for Tinker Bell, and she flew to him. When Wendy saw the fairy, she was amazed. She
wanted to talk to Tinker Bell, but Tinker Bell didn't like Wendy. She didn't want to be friends. She
flew into the bathroom.

“So, where do you live now?” asked Wendy.

“I live in the Neverland with the Lost Boys,“ said Peter. “They are boys who were lost when they
were babies and their parents never found them, so they don't have mothers."

“Oh, the poor boys!" cried Wendy.

“Will you fly to the Neverland with me and be a mother to the Lost Boys?” asked Peter.

“I can’t!” said Wendy. “I can’t fly!”

“I'll teach you,” said Peter.

“Will you teach John and Michael, too?” asked Wendy.

Wendy woke her brothers, and they jumped out of bed.

“All right,” said Peter. “Just think lovely thoughts and they will lift you up in the air.”

Peter blew fairy dust on them and they began to fly around the room. Up and down they went,
and round and round.

“This is such fun!” cried the children. “Let’s go outside!”

Peter took Wendy's hand, and the four children flew out of the window and into the night sky.

When Mr and Mrs Darling came home, their three beautiful children were gone.
