period = 7
periodicity = 1
X =  3.12777 ( equation 1 )

multiply by 10 on the both right hand side and even left hand side of the equation 1

⇒ 10 × X = 3.12777 × 10
⇒ 10X = 31.2777  ( equation 2 )

subtracting equation 2 from equation 1

⇒ 10X = 31.2777 ( - ) X = 3.1277
⇒ 9X = 28.1500
⇒ X =

"we need now remove the decimal point in the numerator for that we need to multiply with 100 for both the numerator and denominator "
X =  ( this is after multiplying with 100 )
⇒ X =
∴ the value of X =
