Question

[Phúc Lâm Từ Công]

(-4/5 + 4/3) + ( (-5/4+4/15)-7/3

Answer 1

[🤣🤣🤣 Ŧùɔ]

Giải :

\(\left(\frac{\text{-4}}{\text{5}}+\frac{\text{4}}{\text{3}}\right)+\left(\frac{\text{-5}}{\text{4}}+\frac{\text{4}}{\text{15}}\right)-\frac{\text{7}}{\text{3}}=\left(\frac{\text{-4}}{\text{5}}+\frac{\text{4}}{\text{3}}+\frac{\text{4}}{\text{15}}-\frac{\text{7}}{\text{3}}\right)-\frac{5}{\text{4}}\)

\(=\left(\frac{\text{-12}}{\text{15}}+\frac{\text{20}}{\text{15}}+\frac{\text{4}}{\text{15}}-\frac{\text{35}}{\text{15}}\right)-\frac{\text{5}}{\text{4}}=\frac{\text{-23}}{\text{15}}-\frac{\text{5}}{\text{4}}=\frac{\text{-92}}{\text{60}}-\frac{\text{75}}{\text{60}}=\frac{\text{-167}}{\text{60}}\)
