2) 2

3) 2

4) 2

5) 4

Пошаговое объяснение:

1) 7,97 округляем с прибавлением 1 к предыдущему числу, т.к.7 больше 5

2) Данную дробь переводим в другой вид (без целых чисел); получаем дробь 29/6. Затем делим 29 на 6 и получаем 4,83333333 (число будет округляться без прибавления единицы к предыдущему числу, т.к. 3 меньше 5)

3) По другому данный дробь 4,(18) можно показать как 4,1818181....18. Округляя до тысячных получим число 4,181

4) 100 см - 1 метр. Переводим 382 см в метры и получаем 3,82 м. С точностью до десятых получим 3,8.

5) Диаметр равен радиусу умноженному на 2. Следовательно, диаметр получим 4,14•2=8,28. С точностью до десятых будет 8,3 (мы округляем с прибавлением 1 к предыдущему числу, т.к. 8 больше 5)

Помогите пересказать данный текст на английском.
As soon as Fay woke up, she knew this birthday was going to be very special. It was a sunny morning and a gentle breeze was blowing in through the window. "A perfect day for a balloon ride!" Fay said excitedly to herself. Half an hour later, her friend Bob picked her up in his car. For her birthday present, Bob, a pilot, was taking Fay for a ride in a hot-air balloon. Fay was thrilled when she saw the huge, bright yellow hot-air balloon. Bob made sure that everything was okay, then they climbed carefully into the basket. Moments later, the balloon began to rise slowly into the air. "This is fantastic!" she shouted cheerfully to Bob. "Happy Birthday!" I'm glad you like your present!" he replied. Suddenly, the smile disappeared from Bob's face. Dark clouds were racing towards them and, before he could say anything, there was a loud rumble of thunder. The balloon shook violently from side to side. "Oh, no!" screamed Fay. "We're going to die!" Just as Bob was reaching for the radio, there was a bright flash of lightning. Fay fell backwards and hit her head, and everything went black. When Fay opened her eyes, she saw Bob's worried face in front of her. "Are you alright?" he asked anxiously. "The balloon went down," he explained, "but fortunately we're landed in a tree. I've already radioed for help." Fay looked over the side of the basked and realised that they were handing from a branch. "Don't worry," said Bob calmly. "It'll hold us. At that moment a fire engine appeared. Its siren was wailing and its red lights were flashing brightly. Two firefighters jumped out and, five minutes later, Fay and Bob were standing safely on the ground. "We're safe at last!" Fay cried. "Fay, I'm sorry," replied Bob. "It wasn't quite what I had in mind, but I'm sure you won't forget this birthday!"
