Question

6. (a) Express 2.15 in p/q bar on 15

Answer 1

Step-by-step explanation:

solution

let us assume 2.15 as x

x - 2.15151515... equation 1

10x - 21.515151515... equation 2

100x -215.151515... equation 3

so let us subtract eq 3 - eq 1 = 213.

you will have to subtract 100x - 1x = 999x

now, x= 213/999 after simplifing you will get 71 /333 that is the answer .so, hence q is not equal to 0
