__________________________

• 0.3333.......

LET 0.3333...... be X

Then x = 0.3333....... (1)

10x = 3.3333........ (2)

Subtract (1) from (2)

Then,

9X = 3

= = > x = 3/9

= = > x = 1/3

__________________________

• 5.2222........

Let 5.2222....... be x

Then x = 5.2222........ (1)

10x = 52.2222........ (2)

Subtract (1) from (2)

Then,

9x = 50

= = > x = 50/9

__________________________

• 0.4040........

Let 0.4040........ be x

Then x = 0.4040........(1)

10x = 4.0404........(2)

100x = 40.4040........(3)

Subtract (1) from (3)

Then,

99x = 40
