Answer :

You have half a dollar or 50 cents. 

Another way to think of it. One tenth of a dollar is a dime. 5 dimes is 50 cents. 

Answer: 
50 cents
Lets split a dollar into 100 pennies! So 1 one-hundreths of a dollar would be 1 cent. To make this as easy as possible all you would need to do is [tex]100/5[/tex] and that should give you your answer, adding a cent sign after it.

Your answer should be 20 cents(:
