Volgvan

Answer:

Part A: 30%

Part B: 45000%

Part A: You need to divide $54.00 by $180.00, when you do that, you get the answer 0.3. You convert it to percentage by doing 0.3 multiplied by 100 which give you 30. Put a percent behind it and you have 30% as your final answer.

Part B: You need to divide 81,000 by 180 which gives you 450. Then you then have to do 450 multiplied by 100 which gives you 45,000. You then add the percentage behind and you have 45000% as your final answer.
