If it measures a maximum of 30cm, which most rulers do it's 15cm.

Five eighths of an inch on a ruler would be located between the half-inch mark and the three-quarter inch mark.
Every half inch.
It is 2/10 past the one inch mark on a ruler.
The answer depends on where the one tenth mark is. Most likely it would represent a millimetre.

On a ruler, 4.5 mm is slightly less than half a centimeter. It is located just past the 4 mm mark and before the 5 mm mark. The distance is roughly the thickness of a credit card or a thin hair. If using a metric ruler, it will be clearly marked, usually with a shorter line than the 5 mm mark.
On a ruler, .30 inches is slightly less than one-third of an inch. It can be found by measuring just a bit beyond the quarter-inch mark (0.25 inches) and before the half-inch mark (0.5 inches). If your ruler has 1/16 or 1/32 inch markings, .30 inches would be between the 5/8 inch and 3/8 inch marks. It may be helpful to use a decimal ruler or a ruler with finer increments for precise measurement.
On a standard ruler, 1.2 cm is slightly more than one centimeter but less than one and a quarter centimeters. It can be found just past the first centimeter mark, roughly one-fifth of the way toward the second centimeter mark. If you're using a metric ruler, it will be the second small line after the 1 cm mark.
