hi

Step-by-step explanation:

2/5 = -8/20] and [1/2 = 10/20]

are -7/20,-6/20,-5/20,-4/20,-3/20,

-2/20,-3/20,-4/20,-3/20, -2/20.

10 rational numbers between -3\4 and 5\6:

LCM of 4 and 6 is 12

-3/4 x 3/3 = -9/12

5/6 x 2/2 = 10/12

Now multiply the fractions with 11 (10+1)

-9/12 x 11/11 = -99/132

10/12 x 11/11 = 110/132

So,  the required reational numbers are:-

1/132 , 2/132 , 3/132 , 4/132 , 5/132 , 6/132 , 7/132 , 8/132 , 9/132 , 10/132....

Or directly can be found by:

{ -9/12 to 10/12 }

-8/12 , -7/12 , -6/12 , -5/12 , -4/12 , -3/12 , -2/12 , -1/12 , 1/12 , 2/12 ,.......
