Convert the following to fractional form in lowest terms. The answer is 13/9.
Can someone show me the steps to this. Thanks.

1.4 with a dot above the 4 to indicate and endless number of 4's.

Examples:
0.4 = 04/10 = 2/5.
3.68 = 368/100 = 184/50 = 92/25.

As a rule, something of the form 0.xxxxxx... with an infinite amount of x'es (and x being any digit), it can be written in fractional form as x/9

Maybe rearranging d-glitches post will make it clearer

   10x   =   14.4444
 -   x   =  - 1.4444
------      ---------
  ???    =     ???

Open in new window


do both subtractions then solve for x
