Question

Tính nhanh

3/4 - 0,25 - (7/3 + - 9/2) - 5/6

Giúp mình nha!!!

Answer 1

\(=\)\(\frac{1}{2}\)-\(\frac{-13}{6}\)-\(\frac{5}{6}\)

\(=\)\(\frac{3}{6}\)-\(\frac{-13}{6}\)-\(\frac{5}{6}\)

\(=\)\(\frac{11}{6}\)

Answer 2

\(\frac{3}{4}-0,25-\left(\frac{7}{3}+\frac{-9}{2}\right)-\frac{5}{6}\)

\(=\frac{3}{4}-\frac{1}{4}-\left(\frac{14}{6}+\frac{-27}{6}\right)-\frac{5}{6}\)

\(=\frac{1}{2}-\frac{-13}{6}-\frac{5}{6}\)

\(=\frac{3}{6}+\frac{13}{6}-\frac{5}{6}\)

\(=\frac{16}{6}-\frac{5}{6}\)

\(=\frac{11}{6}\)
