Answer 1

lcm =35

-3/7×5/5=-15/35

2/5×7/7=14/35

RATIONAL NO. ARE

Answer 2

Answer:

To find the rational no. Between -3/7 and 2/5, we have to use this formula -

1/2*(a+b)

Now,

1/2*(-3/7+2/5)

=1/2*(-15+14/35)

=1/2*-1/35

=-1/70. This is 1st no.

2nd no. = 1/2*(-1/70+2/5)

=1/2*-1+28/70

=1/2*27/70

=27/140

3rd no. =1/2*(-1/70+27/140)

=1/2*(-2+27/140)

=1/2*25/140

=25/280

4th no. = 1/2*(-3/7+25/280)

=1/2*(-120+25/280)

=1/2*-95/280

=-95/560

Hope this will help you
