Tìm tập hợp các số nguyên x biết rằng

4\(\dfrac{5}{9}\) : 2\(\dfrac{5}{18}\) - 7 < x < ( 3 \(\dfrac{1}{5}\) : 3,2 + 4,5 \(\times\) 1\(\dfrac{31}{45}\)) : ( -21\(\dfrac{1}{2}\))

tính giá trị các biểu thức A,B,C rồi sắp xếp các kết quả tìm được theo thứ tự nhỏ tới lớn

A=\(\dfrac{2}{3}\)+\(\dfrac{3}{4}\)\(\times\)\(\dfrac{-4}{9}\)

B=2\(\dfrac{3}{11}\)\(\times\)1\(\dfrac{1}{12}\)\(\times\)(-2,2)

C=\((\)\(\dfrac{3}{4}\) - 0,2 \()\) \(\times\)\((\) 0,4 - \(\dfrac{4}{5}\) )
