My best friend is Thanh An. We came to the same Archimedes School, and we have been friends for 1 year. Thanh An is not short and not tall, he has a normal height. He had a short black hair and a big black eyes. He is very kind and smart, especially in Math. He is funny too, he makes me laugh even when I feel bad. I like to be friends with him. Because he is very smart at Math, we created a Zalo group to do our homework. I will tell you my secret: I sometimes copy his Math homework too (HAHAHA). I hope that I can be friends with him forever.
Nếu thêm cả tử và mẫu cùng 1 số thì hiệu 2 phân số cũng không thay đổi.
Hiệu 2 phân số cũ là:
\(11-2=9\)
Ta có sơ đồ:
Tử số mới: |----|----|----|----|
Mẫu số mới: |----|----|----|----|----|----|----|
Hiệu số phần bằng nhau là:
\(7-4=3\left(phần\right)\)
Tử số mới là:
\(9:3.4=12\)
Số đó là:
\(12-2=10\)
