Question

express 2.015(15 is bar) in the form p/q where p and qare integers and qis not equal to zero

Answer 1

2.015
we want to remove the zero
20.15
100 x = 20151.5151
100 x -x = 20.15-20151.51
9 x= 20131.36
x= 20131.36 ÷ 9
x=

Answer 2

Answer:

2.015 {bar on 15}

so let's take out 0 from 2.015

hence 10x=20.15 { bar on 15}...........(i)

100x=2015.15{bar on 15}..................(ii)

by subtracting (i) from (ii)

100x=2015.15

-10x=. 20.15

90x=1195

x=1195 =13.27(appx.)

90
