The decrease in the visitor numbers on Monday = 845 - 169 =  676

 

This as a fraction of the number on Sunday is 676/845

To find this as a percentage just multiply by 100, so the percentage decrease is 100*676/845 = 80%

Alan I just don't get one thing, why are we dividing 676 by 845 and making a fraction as 676/845 ? That's only what I have a doubt on !

You are asked for the decrease in numbers (which is 676) to be expressed as a percentage of the original (i.e. Sunday's) number (which is 845), so you must have decrease/original. Then you simply turn this fraction into a percentage by multiplying it by 100.
