Answer 1

HEYA MATE, HERE IS UR ANSWER ________________

Changing all the terms into p/q form

0.8=8/10

0.9bar

Let x = 0.999...______(1)

Multiplying with 10 both the sides

10×x=10×0.999...

10x=9.999......_______(2)

Subtracting equation (1)from (2)

10x=9.999..
-x=0.999...

9x=9
x=9/9
x=1


0.67bar
Let x =0.676767....______1)

Multiplying by 100

100x=100×0.676767....

100x=67.676767...... (2)

Subtracting (1)from ( 2)

100x=67.676767
- x=0. 676767

99x=67

x=67/99

Now adding all three

0.8 +0.9 bar +0.67 bar

=8/10 +1+67/99

=4/5 +1+67/99

= 396+495+335/495

= 1226/495
