Question

express 0.40 bar in p/q form​

Answer 1

Answer:

40/99

Step-by-step explanation:

Let(x=0.40bar)×100

100x=40.40bar

100x=40.40bar

- x= 0.40bar

99x=40

x=40/99

Answer 2

Step-by-step explanation:

let x = 0.40bar - 1

multiply both sides by 100

so, 100x = 40.4040 bar -. 2

subtract equation 1 from 2

100x - x = 40.4040 bar - 0.4040 bar

so, 99x = 40

x = 40/99

so,0.4040 bar can be expressed in the form of p/q as 40/99
