For Each coin, state its worth as a percentage of $1?

Answers

Answer:5. is 500%

Step-by-step explanation:

4. Is 250%, and 5. Is 500%

Explanation:
For #4, the coin is equal to $2 1/2, or $2.50. Since the question is asking the worth of each coin as a percentage of $1, $2.50 will be a percentage greater than 100%. $2.50 is 2.5x $1, so if $1 is seen as 100% in this problem, we can do 100 x 2.5. This is how you get the answer of 250%

You use the same method for question 5, except $5 is 5x $1, so we can do 100 x 5 to get 500%
