Question

this is my third time no one answer me ​

Answer 1

Answer:

a.) 675/1000

b) let x = 4.3222222....

10 x = 43.222222 .... (1)

100 x =432.222222.... (2)

(2) -(1)

= 99 x = 432-43

= x = 389/89

c) let x =0.322222....

10 x =3.222.... (1)

100x = 32.2222.. (2)

On (2)-(1)

we get

99x= 32-3

x =29/99
