Question

Express 2.23(3bar) in p/q form

Answer 1

X=2.233

Multiply by 10

10x=22.33

Subtract first equation from second equation

9x=20.1

X=201/90

=67/30

Answer 2

Answer:

let x equal to 2.23333333........equation 1

on multiplying both sides 10 on equation 1

10×x=10×2.3333..........

10x=22.333333..........equation 2

on multiplying both sides 100 on both sides in equation 2

100×x=100×22.333333......

100X=223.3333333.........equation 3

NOW subtracting equation 3 by equation 2

100x-10x=223.33333333.......-22.33333333.........

90x=201

x=201/90

x=67/30

2.23 =67/30
