Question

express 0.27 bar in the pby q form

Answer 1

let assume that 0.272727 be x

x = 0.272727     (1)

multiply both sides by 100

we are multiplying both sides by 100 because if there is bar on 1 digit we have to multiply by 10 and when 2 then by 100 and so on

100x = 27.272727           (2)

subtract (1) from (2)

100x = 27.272727

-    x =   0.272727

99x = 27

x = 27/99
