Answer 2

Hi friend,

Given numbers,
-2/5 and 1/2
LCM is 10,

-2/5×2/2 and 1/2×5/5
-4/10 and 5/10

Multiply 2/2 for both numbers,
-4/10×2/2 and 5/10×2/2
-8/20 and 10/20

-8/20<-7/20<-6/20<-5/20<-4/20<-3/20<-2/20<-1/20<0<1/20<2/20<3/20<4/20<5/20<6/20<7/20<8/20<9/20<10/20

-2/3<-7/20<-6/20<-5/20<-4/20<-3/20<-2/20<-1/20<0<1/20<2/20<3/20<4/20<5/20<6/20<7/20<8/20<9/20<1/2

So,17 rational numbers between the given numbers are
-7/20,-6/20,-5/20,-4/20,-3/20,-2/20,-1/20,0,1/20,2/20,3/20,4/20,5/20,6/20,7/20,8/20 and 9/20

Hope it helps
