+  Why will an error occur when this program runs? 
+  Try playing computer with the example to work out what is going on
+
+  1. The function won't run because we are not invoking the function,
+  2. we have been declared one variable with const and this can not reassigned after, const decimalNumber also has a fixed value
+  3. To work efficiently we should assign the parameter =+ inside the function and declare the var decimalNumber
+  4. we call the function correctly with its respective argument
+
+    function convertToPercentage(decimalNumber) {
+      const decimalNumber = 0.5;
+      const percentage = `${decimalNumber * 100}%`;
+
+      return percentage;
