Question

if the decimal0.d25d25d25--- is expressible in the form of n/27 then d+n must be

Answer 1

Let x = 0.d25.....
1000x = d25.d25......
=> 999x = d25
=> x = d25/999
Now, it is expressible in the form n / 27
=>d25 / 999 = n / 27
=> d25 = 37n
By hit and trial, we have n = 25 and d = 9.....

Thus, n + d = 25 + 9 = 34
Here you go...... Hope my ans. satisfies u
