Question

insert five rational number between -2/5and -1/3 . Pls explain allso

Answer 1

We are given, -2/5 and -1/3

Multiply denominator and numerator of -2/5 and -1/3 by 3 and 5 respectively.
to get the same denominator

-2/5 = -2*3/5*3 = -6/15 and -1/3 = -1*5/3*5 = -5/15 

We have to find 5 rational numbers so multiply both -6/15 and -5/15 by 6/6
 
 = -6*6/15*6 = -36/90   and -5*6/15*6 = -30/90

So, required five rational numbers are -35/90,-34/90,-33/90,-32/90 and -31/90
