it is a 1/4,you need to say it as what is a 1/2 of a 1/2 which is a 1/4,
to work it out you times the top number together 1x1 which is 1 and 2x2 which is 4 so 1/4

0.5 is exactly the same as 0.50, 0.500, 0.5000, 0.50000 and any other way you wish to write it 
The . is the decimal point and when people say "to two decimal places" or "three decimal places" refers to how many numbers you quote after the decimal point.

you are not dealing with whole numbers but fractions of numbers so it decreases

so 1 * 0.5 = 0.5 which is same as 1 * 1/2 = 1/2
0.5 x 0.5 = 0.25 which is same as 1/2 * 1/2 = 1/4

Pour yourself a pint of cider and drink half.
Your pint of cider was 1.0 pint, you've now drunk half so you now have 0.5 of a pint.
To make that back up to a whole pint you will need twice what you currently have in there. i.e 0.5 x 2 = 1.0
If you take another gulp and only have a quarter of a pint, 0.25, so you would need 4 times as much to get back up to a full pint... 0.25 x 4 = 1.0
So if we think of it as you having 4 glasses all with a quarter of a pint in, you'd need to pour them all into one.
If you give yourself a top up back to half a pint, 0.5 if you multiplied it with another half pint 0.5 you'd have 1 full pint, but you'd need to put it into 4 glasses... So 1 pint divided by 4 glasses would mean a quarter of a pint in each which is 0.25
Keep pouring yourself a pint until it sinks in
