Question

Answer 1

\(a,A=\dfrac{1,11+0,19-13.2}{2,06+0,54}-\left(\dfrac{1}{2}+\dfrac{1}{4}\right):2\\ =\dfrac{1,3-26}{2,6}-\left(\dfrac{2}{4}+\dfrac{1}{4}\right):2\\ =\dfrac{-24,7}{2,6}-\dfrac{3}{4}:2\\ =-\dfrac{19}{2}-\dfrac{3}{8}\\ =-\dfrac{79}{8}\\ B=\left(5\dfrac{7}{8}-2\dfrac{1}{4}-0,5\right):2\dfrac{23}{26}\\ =\left(\dfrac{47}{8}-\dfrac{9}{4}-\dfrac{1}{2}\right):\dfrac{75}{26}\\ =\left(\dfrac{47}{8}-\dfrac{18}{8}-\dfrac{4}{8}\right).\dfrac{26}{75}\\ =\dfrac{25}{8}.\dfrac{26}{75}\\ =\dfrac{13}{12}\)

`b, A<x<B`

`=>-79/8 <x< 13/12`

Mà `x` nguyên

`=>x in {-9;-8;-7;-6;-5;-4;-3;-2;-1;0;1}
