Answer 1

let 3.425(bar on 5)=X (equation-1)

Multiply both sides by 100 in equation-1

3.425(bar on 5)x100=Xx100

342.5(bar on 5)=100X (equation-2)

Now, Multiply both sides by 1000 in equation-1

3.425(bar on 5)x1000=Xx1000

3425.5(bar on 5)=1000X (equation-3)

Now, subtract equation-2 from equation-3

1000X-100X=3425.5(bar on 5) - 342.5(bar on 5)

900X=3083

X=3083/900(ans)
