Answer:

Multiplying by 10 both sides,we get

10x=4.7777…eq(ii)

Multiplying again by 10 both sides,we get

100x=47.7777…eq(iii)

On subtraction eq.(ii) from eq.(iii),we get

(100x-10x)=(47.7777…)-(4.7777)

= 90x = 43 = x = 43/90

hence,0.47=43/90

Answer:43/90

Explanation:

Let x = bar0.47, x = 0.47777. (a)

We need to mulgiply both sides by 10 to get 10x = 4.7777. (b)

We need to subtract (a) from (b) to get

10x=4.7777.
- x=0.4777.
=9x=4.3

We can also write 9x = 4.3 as x = 4.3/9 or x = 43/90.

Therefore, on converting bar 0.47 in the p/q form,,we get the answer as 43/90.
