Пошаговое объяснение:

8ц 1/8 : 2ц 1/2 - (1ц 1/4 + 1ц 2/3) = 65/8 ÷ 5/2 - ( (1+1) + (1/4 + 2/3) ) = 65/8 × 2/5 - (2ц + 11/12) = 13/4 - 2ц 11/12) = 13/4 - 35/12 = 1/3

Hi Igor,
How are you keeping? Has spring arrived in St Petersburg yet? Over here the first flowers are out and the trees are turning green. I love this time of year.
At school, everything is pretty boring, as usual. But last week we had a meeting about careers with a special adviser, and it really made me think. She said we are old enough to start thinking about the future and we should decide which direction we want to take in life. I found it a bit scary! For example, next year, when we choose our subjects for A level, she told us we have to think about career options and even university studies, though plenty of people get a good job without going to university. But I just can't make up my mind! I don't want to be unemployed like so many young people here in Liverpool, but I really can't believe that I'll be studying for the next five or six years! One of my neighbours studied for a degree but he dropped out at the end of his second year and now he's got into advertising — he's making loads of money and he has a new BMW!
You know me! I'm quite good at languages but I'm hopeless at maths and science, and I really don't think I'm the academic type. My parents keep telling me about all the people who fail in life because they don't study hard enough, and I'm getting fed up with all this pressure to succeed. What do you think I should do?
Write back soon and tell me!
Love
Maggie
