Bài làm
Gọi số cần tìm là x.
Ta có: \(-\frac{8}{6}< \frac{ }{2}< -\frac{3}{6}\)
\(-\frac{8}{6}=-\frac{16}{12}\)
\(-\frac{3}{6}=-\frac{6}{12}\)
Mà -16 < x < -6
=> x = -15, -14, -13, -12, -11, -10, -9, -8, -7.
Vậy x = -15, -14, -13, -12, -11, -10, -9, -8, -7.
# Chúc bạn học tốt #
\(\frac{-8}{6}< \frac{-2}{2}< \frac{-3}{6}\)
#Học Tốt#
thay vào ta có -8/6 < x/2< -3/6
Qui đồng mẫu ta có.-8/6 < (x * 3)/6< -3/6
suy ra x * 3 \(\in\)-7 , -6,-5,-4

\(\frac{-8}{6}< -\frac{2}{2}\left(=\frac{-6}{6}\right)< -\frac{3}{6}\)
gọi số cần tìm là x
\(\frac{-8}{6}< \frac{x}{2}< \frac{-3}{6}\)
\(\frac{-8}{6}< \frac{3x}{2.3}< \frac{-3}{6}\)
\(\frac{-8}{6}< \frac{3x}{6}< \frac{-3}{6}\)
-8<3x<-3
=>3x\(\in\){-7;-6;-5;-4}
vì 3x chia hết cho 3
=>3x =-6
x=-2
