Пошаговое объяснение:

1.Б

2.А

3.Г

Все очень просто в первом 4 и 3 не сокращаются,2 и 9 тоже при умножении 2×4=8 а 3×9=27 получается 8/27

Во втором мы просто переворачиваем 7/3

и получается 2/3:3/7 тройки сокращаются и получается 2/7,кстати тут А и Г одинаковый ответ, не знаю почему.

В 3 мы просто 3 умножаем на 4 и на две запятые уходим влево

NONE27: Спасибо!

So, as unemployment reaches record levels, it's time to discuss what you can do to get a job. And we're lucky to have Jane Longley from the Department of Employment with us in the studio today, who can give some advice to those who are currently looking for work. Welcome, Jane. Hi. It's nice to be here. So, how can today's job hunters get back to work?

01:27
So, a person looking for a job faces a number of challenges. A person looking for a job faces two main problems. One, actually getting an interview, and two, making sure that they perform well in the interview itself. And I'd like to, if I may, give some helpful advice, so to speak, on what you can and can't do.

01:44
That sounds great. So, let's start with the job search. Right. First, you have to make sure you have an up-to-date resume. Emphasize the positive aspects of your career and describe the range of skills you have that might be useful to an employer.

02:00
For more information on preparing a resume, see your local job center's free brochure. Whenever you have a resume, you need to get it into the hands of possible employers. There are several ways to do this. Such as? First, you should check the newspapers regularly for job openings.

02:19
Think about what kind of work you could actually do. It may well be that you have the skills you need to do a job you haven't thought about before, so don't limit yourself unnecessarily. Also, make sure you ask your family and friends about jobs, as up to 50% of jobs are never advertised in the newspapers at all.

02:40
Another thing you can always do is make a list of organizations that need your skills and just send them a copy of your resume. The employer may have a job opening, or they often put your resume in their files and contact you later when a position comes up.

02:57
Okay, let's pretend that you finally got an interview. What do you need to do to make a good impression? I'm glad you asked me that. Well, a lot of things are really just common sense. For example, make sure you get a good night's sleep the night before. That way you'll look and feel your best that day.

03:15
Second, make sure you wear the right clothes for work. If it's an office job, you should wear formal clothes, but for factory or store work you can often wear something more casual. But you should always look clean and tidy. And always make sure you arrive, say, 10 minutes early.
03:34
That way you can sit back and relax for a few minutes before the interview. Another good tip is to be very nice to the receptionist, as in many organizations he or she often has a surprisingly large influence on who gets the job. And when you meet the interviewer, smile pleasantly and shake his or her hand,

03:55
But don't sit down until you are invited. I think I hardly need to add that you should not smoke or chew gum. Near the end of the interview, the interviewer may ask you if you have any questions, so try to come up with one or two intelligent questions before the interview. It's easier if you've learned something about the organization, done your research, so to speak.

04:16
Finally, when the interview is over, never ask if you got the job. If the interviewer wants to tell you right away that you have a job, he or she will. Well, thank you, Jane. I'm sure many of our listeners will find this very helpful.
