65% of the Coins in Tims bank are quarters

Explanation:

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
