Question

please answer the question ​

Answer 1

Answer; 1/2,19/10,9/25

Answer 2

Step-by-step explanation:

1) Let x = 0.5

x = 0.5555.......... - eqn-1

Multiplying by 10 both sides

10 x x = 10 x 0.5555.....

10x = 5.5555....... - eqn - 2

Subtracting eqn - 1 from eqn - 2

10x = 5.5555......

- x = 0.5555......

_______________

9x = 5

x = 5/9. Ans

2) Let x = 3.8

x = 3.8888..... - eqn - 1

Multiplying by 10 both sides

10 x x = 10 x 3.8888.........

10x = 38.8888....... - eqn - 2

Subtracting eqn 1 from 2

10x = 38.8888.......

- x = 3.8888.......

________________

9x = 35

x = 9/35
