How can you write one half as a decimal?

Answer 1

0.5

To figure it, you can do the division problem 1 divided by 2

If you use a calculator, just type it in; if by hand, do long division with:

_0.50___

2|1.00

So 1 divided by 2 is zero, subtract 1-0 = 1 bring down a zero, 10 divided by 2 is 5 with no remainder, so you're done. You can keep adding more zeros to the right until you have no remainder, or it starts repeating.
