Cần khẩn cấp!!!

Ai nhanh nhất cho 3 tick

Answer 1

[Đoàn phương linh]

   (2/2017 + 2/2018) / (5/2017 + 5/2018)

= 2 x (1/2017 + 1/2018) / 5 x (1/2017 + 1/2018)

= 2/5 (vì (1/2017 + 1/2018) khác 0)

Answer 2

[Nguyễn Phạm Hồng Anh]

\(\frac{\frac{2}{2017}+\frac{2}{2018}}{\frac{5}{2017}+\frac{5}{2018}}\)

\(=\frac{2\left(\frac{1}{2017}+\frac{1}{2018}\right)}{5\left(\frac{1}{2017}+\frac{1}{2018}\right)}\)

\(=\frac{2}{5}\)

Study well ! >_<
