Answer:

(1)-5/12

(2)given below

(3)given below

Step-by-step explanation:

1) p+q/2

=-2/3+1/4

___________

2

= lcm of 3and 4 we 12

=-8+3/12

_______

2

=-5/12*1/2

=lcm be 12

=-5*6/12

= -30/12= -10/4= -5/2ans

(2) first method

(2)convert these rational number into same denominter

=-3/11= -3*5/11*5= -15/55

= 8/11= 8*5/11*= 40/55

hence 10 rational number be :-

-16/55,-14/55,-13/55,-12/55,-11/55,-10/55,-9/55,-8/55,-7/55

(2)method to do second question:

ans=denominter are same so we get answer directly

=-2/11, -1/11, 0/11 ,1/11, 2/11, 3/11, 4/11, 5/11, 6/11 ,7/11

(3)same method is used in this question also is (2) question ka (1) method

hope it's help you

thank you
