2/5×4 = 8/20×10=80/200

Hi!!!


Rational nos between 1/2 and 2/5=> ⬇⬇⬇⬇

= a+b/2

a=1/2 , b=2/5

= 1/2+2/5 / 2

= 5+4 /10

=9/10. - 1st no.


= a+b / 2

a=9/10 , b=2/5

= 9/10+2/5 / 2

=9+4/10 / 2

=13/10 x 1/2

=13/20 - 2nd no.


= a+b / 2

a=13/20 , b=2/5

= 13/20+2/5 / 2

=13+8/20 / 2

=21/20x 1/2

=21/40 - 3rd no.


Therefore, the three rational nos between 1/2 and 2/5 are- 9/10 , 13/20 , 21/40


Hope it hlpzz.......
