please give me the solutions of each question of this question and I will mark you as BRAINLIEST

Answer 1

Step-by-step explanation:

1)The two rational numbers between 0.1 and 0.3 are 0.2 which can be expressed as 1/5 and 0.25 which can be expressed as 1/4

2)3 1/8= 25/8 (Mixed fraction)

Now 25/8= 3.125.

3) using (a+b) (a-b) = a^2-b^2

=> 16-9

=> 7

4)

Answer 2

Answer:

Step-by-step explanation:

2.    3[1/8]

     = [8*3]+1/8

     =24+1/8

  =25/8

      =3.125

3. using identity [a+b][a-b]=a[sq]-b[sq]

      [4+root3][4-root3]=4[sq]-root3[sq]

                             =   16-3

                             13

4.  rationalisation : 1/[root3-root2]

     =    1*[root3+root2]/[root3-root2][root3+root2]

     =  root3+root2/root3[sq]-root2[sq]

   =  root3+root2/3-2

   =  root3+root2/1

10.  3root3 +root3=4root3

note i will send you the answers personally because i should write it on a sheetof paper and couldnot even click the pic now because i am  using brainly on desktop

if you like you could send me your whatsapp no. personally it is your wish!!!!!
