1.1444444444...

Answer 2

(22)

Given 0.6(bar) + 0.47(bar).   ----- (1)

(i)

Let x = 0.6    ----- (2)

= > x = 0.66...  

Multiply both sides by 10, we get

= > 10x = 6.6    ----- (3)

On solving (2) & (3), we get

= > 10x - x = 6.6 - 0.6

= > 9x = 6

= > x = 6/9

= > x = 2/3.

-------------------------------------------------------------------------------------------------

(ii)

Let x = 0.47.   ---- (3)

= > x = 0.4777.

Multiply both sides by 10, we get

= > 10x = 4.777   ---- (4)

On solving (3) & (4), we get

= > 10x - x = 4.7777 - 0.4777

= > 9x = 4.3

= > x = 4.3/9

= > x = 43/90

------------------------------------------------------------------------------------------

Now,

Substitute both in (1), we get

= > (2/3) + (43/90)

= > (60 + 43)/90

= > 103/90.

Therefore, the final answer is 103/90.

Hope this helps!
