Question

pls solve step by step class 7 ​

Answer 1

Step-by-step explanation:

The rational numbers between -2 and -3

.. ans

A rational number lying between -2 and -3 is 1/2({-2) + (-3)} i.e,-5/2

Now a rational number lying between -2 and -5/2 is

1/2{(-2) +(-5/2)] i.e, 1/2 ×(-9/2)

=-9/4

And a , rational number between -3 and -5/2 is

1/2{(-5/2) +(-3)}

=1/2×(-11/2)

=-11/4

Thus ,we have -2>-9/4>-5/2>-11/4>3

Hence,five rational numbers betweem -2 and -3 are -9/4 ,-5/2,-11/4 etc

6) no. u can do by this formula (n+1)

n =4

(4+1)=5

Hope it help you

!!!! thankyou ♥

By another method u can do it like .. 5) -3/1=-3×9/1×9=-27/9

-2/1=-2×9/1×9=-18/9
