Question

Represent 0.39(bar on 39) in p/q form

Answer 1

Answer:

Step-by-step explanation:

let x=0.393939393...........                     ....(1)

multiply both side by 100

100x=39.3939393939...........................                  .....(2)

subtract 1 from 2

99x=39

x=39/99

x=19/33

Answer 2

Let x = 0.39 ( bar on 39) _______Eqn 1)

Multiply both by 100 .

100x = 39.39 (bar and .39)(Eqn2)

Subtract (1) from (2)

100x - x = 0.39 - 39.39

99x = 39

x = 39/99
