color(red)(7/30)

Explanation:

x= color(blue)0.2333333...

Then multiply both sides of the equation by 10 ( or any multiple of ten) so that the decimal can become a number more easily converted to a fraction.

color(green)(10x = 2.333333...)

Now subtract color(red)x from color(blue)10x

color(green)(10x-x = 2.3333...- 0.23333...)

You get:

color(blue)9x=color(green)2.1

To get rid of the decimal point, times each side by ten or a multiple of ten, to get the decimal point away:

90x=21

Then write 90x=21 as a fraction:

x= 21/90

Then simplify:

x= 21/90=7/30

So 0.23333... written as a fraction is 7/30.
