Пошаговое объяснение:

1) 4/9+1/6 - Т.к. - на - дают +, далее слаживаем дроби и получаем 11/18

2)-5/8+1/6 - Раскроем скобки, далее вычисляем сумму и получаем -11/24

3)21-34/36 - Запишем числители под наименьшим общим знаменателем, вычисляем разность и получаем -13/36

4)- 27+16/60 - Запишем числители под наименьшим общим знаменателем, слаживаем числа и получаем -43/60

5)9-16/30 - Запишем числители под наименьшим общим знаменателем, вычисляем разность и получаем -7/30

6)-11/25+3/10 - Раскроем скобки, далее вычисляем сумму и получаем -7/50

1.    Where does Jack come from?
2.    Why is Jack sad?
3.    What does he want to achieve?
4.    Why does Jack call himself a loser?
5.    What does Emily think is important to be successful?
6.    What does Jack think is important to be successful?

Misha:   That song about "celluloid heroes" is actually very sad, Jack. 
Jack:        You're right. Hollywood Boulevard always makes me sad. 
Rob:        But why?
Jack:        It reminds me that all my dreams are unrealistic, and I'll never
                 achieve anything. 
Rob:        And what would you like to achieve?
Jack:       Oh. it's a typical Hollywood story. Two years ago I left my parents' little farm in 
                 Texas and came to LA. In my home town everybody said that I was good-looking and good 
                 at acting. When I came to LA, I was full of ambition. I was sure that very soon somebody 
                 would notice me and give me a part in a movie. But nothing happened. I've been working 
                 as a tour guide for two years now, and nobody has asked me to be in a movie yet. 
                 So here I am, a typical Hollywood loser. 
Emily:    Oh, don't give up so easily, Jack. Hard work and a bit of talent are the only things that matter. 
                 And, of course, you have to believe in yourself.
Jack:       Yes, I used to think so too, but in fact what you need are good
                 connections and a lot of luck. 
Mark:     But think about people like Walt Disney, Sylvester Stallone, Sharon Stone, Sean Connery or 
                 Jack Nicholson. They had no connections, but they became legends.
Jack:       They are the lucky exceptions. And besides, they were still quite young when they were discovered. 
                 I'm already twenty-five, and nowadays stars start their careers very early. Take Macaulay Culkin, for example.
Mark:     You're not quite right, Jack. An early start doesn't guarantee success. Macaulay Culkin 
                 was a very promising child actor when he was in "Home Alone", but now that he's grown up, 
                 he doesn't get any more roles. 
Jack:       You may be right, but I should probably think of another career. I can't work as a tour guide all my life.
