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,

$80 - 28 = 52 \text{ }$quarters

Now we express this as a fraction,

$\frac{52}{80} \text{ }$Coins in Tims bank is a quarter

To work out a percentage we multiply by 100

$\frac{52}{80} \cdot 100$

$= \frac{52 \cdot 100}{80}$

$\frac{= 52 \cdot 5}{4}$

$= 13 \cdot 5$

=65%

so 65% of the Coins in Tims bank are quarters
