My favorite pet is a dog. I love dogs because they are cute and loyal to their owners. I have a dog at home, his name is Ki. Ki is a dog which I have been keeping for four years. It is a Poodle so it is really friendly. It has bushy and soft brown fur and glistening eyes. When I look at his big, beautiful eyes, I just melt like ice cream on a hot summer day. Ki takes pleasure in sniffing everything when he has nothing particular to do. Everyday, I give her some biscuits and milk in the morning, rice and meat in the afternoon. Whenever I go out in the evening, he always accompanies me like he wants to protect me. Ki seems to be one of my best friends, I love him very much!

Bài 1: Giải:

Từ 1 ⇒ 9 có số trang là : (9 - 1) x 1 + 1 = 9(trang)

⇒ Từ 1 đến 9 cần đánh số chữ số là: 9 x 1 = 9(chữ số)

Từ 10 ⇒ 99 có số trang là: (99 - 10) x 1 + 1 = 90(trang)

⇒ Từ 10 đến 99 cần đánh số chữ số là: 90 x 2 = 180(chữ số)

Từ 100 ⇒ 452 có tổng số trang là: (452 - 100) x 1 + 1 = 353(trang)
