+1. Undeclared variables are automatically declared when first used. As a parameter in the 'convertToPercentage' function,
+'decimalNumber' is (automatically) already declared. trying to declare it again with 'const' will cause a syntax error.
+2. Also, the 'console.log(decimalNumber);' line is outside the function, so 'decimalNumber' is not defined in that scope.
+3 decimalNumber = 0.5; overwrites the argument supplied, and so to make the function work as intended, this line should be removed, so the function does not ignore its input argument.
