Question

Express the following into the form of p /q =0.3181818.....

Answer 1

let x= 0.3181818...------(1)
10×(1)

10x =3.181818.....-------(2)

1000 × (1)

1000x = 318.181818...--(3)

subtract (2) from (3)

1000x = 318.181818...
10x = 3.181818...
________________
990x = 315.0

x = 315/990

x= p/q =9×5×7/9×5×22
=7/22
