Các bạn giải nhanh giúp mình nha! 

Câu 1: Thực hiện phép tính bằng cách hợp lí

\(\frac{15}{35}+\frac{7}{21}+\frac{19}{34}-1\frac{15}{17}+\frac{2}{3}\)

\(\left(-2\right)^3.\left(\frac{3}{4}-0,25\right):\left(2\frac{1}{4}-1\frac{1}{6}\right)\)

\(16\frac{2}{7}:\left(-\frac{3}{5}\right)+28\frac{2}{7}:\left(-\frac{3}{5}\right)\)

Câu 2: Tìm x biết

\(2.x-\frac{5}{4}=\frac{20}{15}\)

\(1,5:0,3=x:-15\)

\(|2x-1|=2\)

Câu 3: Thực hiện phép tính hợp lí

\(\frac{11}{12}.\frac{15}{33}+\frac{11}{12}.\frac{2}{22}\)

\(3/3\frac{1}{8}.11\frac{17}{19}-3\frac{1}{8}.13\frac{17}{19}\)

\(28\frac{2}{7}:\left(-\frac{3}{5}\right)+16\frac{2}{7}:\left(-\frac{3}{5}\right)\)
