3/25 - 11/4 + (-28)/ 25 - 4/3 - 1/4

mn giải giúp e vs ạ

Answer 1

\(\frac{3}{25}-\frac{11}{4}+\frac{-28}{25}-\frac{4}{3}-\frac{1}{4}\)

\(=\left(\frac{3}{25}+\frac{-28}{25}\right)+\left(\frac{11}{4}-\frac{1}{4}\right)-\frac{4}{3}\)

\(=\frac{25}{25}+\frac{5}{2}-\frac{4}{3}\)

\(=1+\frac{5}{2}-\frac{4}{3}\)

\(=\frac{13}{6}\)
