Hi,
Please tell me why I have to use "a" for "hundred" not "one"?
"A thousand is ten times more than a hundred."
Thanks.
 
  • Generally, "one" is used to stress the quantity or amount.

    It's one hundred miles to Belfast [not 2 hundred].

    Similary, "I have eaten one cake" = only one, not more than one.
