The value of 0.4\overline7 will be in the form of fraction is 43/90

To find:

\frac {p}{q} = ??

Solution:

Given : We have to express 0.47 (bar on 7) in the form of p/q.

Let us ASSUME that

x = 0.47777

MULTIPLYING both the sides by 10, we get

10x = 4.7777 ---------(1)

Multiplying both the sides by 100, we get

100x = 47.777 ---------(2)

Subtract equation (2) and (1),

100x = 47.777

10x = 4.777

90x = 43.000

x =\frac {43}{90}

Thus, the value of 0.4\overline 7 will be in the form of fraction is 43/90
