Answer: 53/90

Explanation:

Okie so in order to do this, we need to get rid of the repeating part of the decimal

==============================================================

Right now we have x = 0.58888888888888888...

If we multiply this by 10, we get

10x = 5.888888888888888

And if we multiply by 100 we get

100x = 58.8888888888888

==============================================================

Subtract the two equations

100x = 58.8888888888888

10x = 5.888888888888888

------------------------------------------------- (notice: the repeating part will cancel out)

90x = 53

x = 53/90

This fraction cannot be further simplified
