Cần khẩn cấp!!!

Answer 1

   (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

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

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

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

Study well ! >_<

Answer 3

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

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

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

Answer 4

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

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

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

Answer 5

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

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

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

@Cô phù thuỷ đáng yêu : dùng dấu bằng chứ sao bạn dùng dấu suy ra?

Answer 7

Cảm ơn các bạn

Answer 8

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

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

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

Answer 9

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

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

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