Express 3.222......in p/q form​
beks73 [17]

Answer:

3.22222......  = \frac{29}{9}

Step-by-step explanation:

In this question we have to convert the number given in recurrent decimals into fraction.

Recurrent decimal number is 3.22222.......

Let x = 3.2222.........   -------(1)

Multiply this expression by 10.

10x = 32.2222........... -------(2)

Now subtract the expression (1) from (2),

10x = 32.22222.....

<u>    x = 3.22222.......</u>

9x = 29

x = \frac{29}{9}

Therefore, recurrent decimal number can be written as \frac{29}{9} which is in the form of \frac{p}{q}.
