Lớp 2C có 30 học sinh. Một phần ba số học sinh lớp 2C là nữ. Hỏi lớp 2C có bao nhiêu học sinh nữ? Bao nhiêu học sinh nam?

Gia sử số con ếch và số con cua bằng nhau thì mỗi loại có số con là :

200:2=100(con)

Số chân ếch là : 100x4=400(chân)

Số chân cua là : 100x10=1000(chân)

Số chân ếch hơn số chân cua là :

1000-400=600(chân)

Còn nhiều hơn so với bài toán là : 600-180=420(chân)

Mà cứ bớt 1 con cua thêm 1 con ếch thì hiệu số chân cua và ếch giảm : 4+10=14(chân)

Cửa hàng mua số con cua là :  100-30=70 (con)

Dear Dan,

I am writing this letter to give you great news on my newly purchased house. I hope you are doing well and sorry for not being in touch for such a long time. I was too busy in moving to new house.

As you know, our old house was not that specious and had only two bedrooms. With addition my baby girl we needed a bigger house. Neighborhood was also not that great and it was very far from Ben's office. It took long time to buy this new house, but believe me this is great one! My son is very happy to be at this new house. We have 3 specious bedrooms, a big size living and dining room and a fully equipped kitchen. My baby girl has a great space to crawl. It has a small backyard with a pet house for our doggy - Raju.

More importantly, this new house is very close to Ben's office. Now he is starting late to office and reaching back home early. Ben is also happy to give quality time for us, instead of wasting his time on long travel and traffic jams.

This Sunday, if you are available please visit our new house; I am sure you will like it.
We can have a lunch together with our families. We will also like to get your creative ideas for decorating our kid's rooms. Please find the address as below.

E8-1103, Lake Town, Near Hyde Park, Harrow.

See you soon!

Lots of love
Suzane

Writing: Write an informal e-mail to a friend telling him/her about your weekend.

Hi friend, (Hi + name of friend, it sounds like a Nigerian spam emailer otherwise, e.g. estafador)

This weekend, I don´t have to work and I usually (suelo?) work weekends. It would be fantastic to meet up with you, (what could or would be? you've not mentioned anything beforehand) but I have an english exam on Monday.... I have also had a very bad time lately because my grandmother and cousin have both been in hospital.

Today, I have improved (He mejorado.... It works the same in english) my english in diferents ways by using both the internet and books. My problem is that I´m not creative in the writing part. If I have to write an e-mail to a friend, I can't think of ideas about what to do, or imagining (imaginar) a free weekend. It´s better for my to talk about my real situation. After my english exam I will have other more important exams. (My dream job is to work with children in public education) ((this bit doesn't fit as it doesn't tie into the rest of the letter. It needs expanding on). I´m sorry that I can´t see you but I promise to see you in the summer.

Regards, Alvaro

Good Work! (Sorry I cant highlight things, as I'm on an iPad) ¡saludos!

One small thing, when you use the indefinite article 'a' when the next word starts with a vowel 'a' becomes 'an'.

e.g. An apple, an architect, an eye. The same applies with a+h. E.g. an hour, an historical event (it's because it's silent)
