1/2×10 = 10/20×10=100/200
2/5×4 = 8/20×10=80/200
rational nos between are 81/200,82/200,83/200.......
2/5×4 = 8/20×10=80/200
rational nos between are 81/200,82/200,83/200.......

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.......
