Question

express 0.47 bar bar on 7

Answer 1

x=0.47 ( a)

Here the periodicity is 1 so we should multiply both sides of the number with 10.

we get 10x= 4.7 (b)

Now we should subtract a from be,

therefore 10x=4.7 - x= 0.47

9x = 4.3

x = 4.3/9

Hence the fractional form or p/q form of 0.47 us 4.3/9
