Explanation:

We have
P = 0.83¯ and Q = 0.62¯
The distance between P and Q = 0.21¯ = x
Expressing this distance in the form of rational numbers, we assume 0.21¯ = x
Number of digit with bar = 1
Number of digit without bar = 1
Therefore, the denominator would be 90
Number of digit after the decimal = 2
Therefore, the nominator = 21 – 2 = 19
Thud x = 19/90
