-// =============> write your prediction here
-// an error will occur because the variable decimalNumber is redeclared inside the function.

-// =============> write your explanation here
-// the fucntion convertToPercentage has a parameter named decimalNumber,

-// there is no need to redeclare the variable or edit it since it is a user input.
