Пошаговое объяснение:

1 1/2 x + 3/8 x = 1 4/8 x + 3/8 x = 1 7/8 x

якщо x = 1 1/7

1 7/8 x = 1 7/8 * 1 1/7 = 15/8 * 8/7 = 15/7 = 2 1/7

Dear Olha Ivanivna,
Last week we went to the centre of Londn and saw wonderful places.I took some photos there.
I learnt a lot about the history of London.It is really exciting and interesting.I heard about the English kings and queens.
But the most interesting story was about King Arthur.
I bought some souvenirs and presents yesterday.
See you soon.
Taras.

Надо перевести эти два текста, без переводчика, помогите пожалуйста!
ANNA:I take lessons in Irish dancing. You might think that is boring, but it’s really good fun and enjoyable. I have a chance to travel to places like Canada and the States to compete. The only thing that matters for me now is to win in the World Championships of Irish dancing in Ireland. I’m going there this month. I’m excited about my hobby. I think it’s a brilliant hobby and people should try it before they say it’s boring.
Tom:When l come home from school l do nothing but relax because l'm very tired after a difficult day at school. I like sitting in front of the TV with popcorn. I'm a bit of a coach potato. My favourite channel is MTV. My mum doesn't like the way l spend time. She says that sitting in front of the TV is a waste of time. I don't agree. We all work very hard at school and it's fair to relax. More than that, l get a lot out of TV. There is nothing l don't know about my favourite groups. And it's fun to be a fan!
