Question

find ten rational numbers between -2/5 and 1/2​

Answer 1

Answer:

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

Answer 2

Answer:

-2/5 &1/2

= L.C.M = 10

= -2/5*2/2= -4/10 *10 = -40/100

= 1/2*5/5= 5/10 * 10. = 50/100

and =: -39/100 , -38/100 ,-37/100 ,-36/100 , -35/100 ,-34/100 , -35/100 ,-34/100 , -33/100 , -34/100 .
