Các bạn giúp mình nhé mình căsân gấp lắm 

Answer 1

[VRCT_Búp Bê Zoke_PK Huỳnh Akj_]

\(\left(\frac{3}{8}+-\frac{3}{4}+\frac{7}{12}\right):\frac{5}{6}+\frac{1}{2}\)

\(=\frac{5}{24}:\frac{5}{6}+\frac{1}{2}\)

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

Ủng hộ mk nka!!!^_^^_^^_^

Answer 2

[Le Thi Khanh Huyen]

\(\left(\frac{3}{8}+\frac{-3}{4}+\frac{7}{12}\right):\frac{5}{6}+\frac{1}{2}\)

\(=\left(\frac{9}{24}-\frac{18}{24}+\frac{14}{24}\right).\frac{6}{5}+\frac{2}{4}\)

\(=\frac{9-18+14}{24}.\frac{6}{5}+\frac{2}{4}\)

\(=\frac{5}{24}.\frac{6}{5}+\frac{2}{4}\)

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