Ahalf-dollar is worth 50 cents. how many half-dollar coins equal one doller

If one is 50 cents, then to get to one dollar we need 2 of those. also, one dollar equals 100 cents, and 50+50=100, so then the answer would be that you need to have 2 coins of the half-dollar to get to 1 dollar. i hope that this  helps you, have a great day! =)

If 50 cents = 0.5 dollars . 1 divided by 0.5 is 2 therefor it will mean that 2 x 50 cents = 1 dollar
