You mean is 8/15 greater than .53? No!. Divide 8/15 on a calculator and you will see they are about the same. Only in a sense 8/15=.5333333......... which goes for as long as you want.
Let mw show you how to always figure something like this out
First note 0 .53 = 53/100
8/15 ??? 53/100
Multiply 100 x 8 and put the result on the left.....multiply 15 x 53 and put the result on the right....so we have.....
800 ??? 795
Whichever side has the greatest number is the side that the greater fraction was on originally
So
800 > 795 means that 8/15 > 53/100
