 // Predict and explain first...
 
 // Why will an error occur when this program runs?
-// =============> write your prediction here
+// Answer below:
+// An error will occur for two reasons, first because there variable "decimalNumber" being decleared
+// The second reason is because the function "convertToPercentage" placeholder has no value when it was called 
 
-// Try playing computer with the example to work out what is going on
+// =============> write your prediction here: 
+// Answer below:
+// I predicted that the code will not work because of the variable (decimalNumber) inside the function,
+// Also because the console.log function is not not calling the function "convertToPercentage" with a value
