1) Let’s given an amount in American dollars (USD) we need to pay. I think obviously it should be a variable. But we have only Euro (EUR). The dollar rate is given too and should be variable too. So, using methods implement the program which prints the amount in euro.
For example: You need to pay 100$. The exchange rate USD/EUR is 1.2. The output is: “for the payment 100$ you need 83.3333 Euro 2) Implement the method that takes two arguments. The second argument specifies what percentage of the first number the method should return. For example: Arguments: (100, 11) -> result is 11
3) Imagine, you should take some % for every exchange operation. Implement this method using the methods from task 1) and task 2) 4) Using the method add for two numbers which we wrote on class implement a method for adding 4 numbers.
