Answer 1

Answer:

Step-by-step explanation:

Here 0.7bar =.77777.........

0.43 bar =0.43434343..

For eq°1

Let ¥=0.7bar

Then 10¥= 7.7777....

On solving

(10-1)¥=7.777....-0.77777

Since. 9¥=7

¥=7/9

Similarly .434343... =43/99

On adding = 43/99+7/9

=43+77/99=120/99 this is your answer

Answer 2

Answer:lets take x as 0.43777...

Then 10x=4.377777...

Now sub 10x-x

=4.37777777....-0.4377777777....

=3.94

9x=3.94

X=3.94/9
