65% of the Coins in Tims bank are quarters

First, we must work out How many quarters Tim has.
we Know he has 80 coins and 28 of them are not quarters so,
the number of quarters Tim has is,

#80-28=52" "#quarters

Now we express this as a fraction,

#52/80" "#Coins in Tims bank is a quarter

To work out a percentage we multiply by 100

#52/80 *100#

#=(52*100)/80#

#(=52*5)/4#

#=13*5#

#=65%#

so 65% of the Coins in Tims bank are quarters
