#### Answer

$\frac{4}{11}$

#### Work Step by Step

As per the information
Original price $ 8.80
New price $ 5.60
Price decrease = Old price - New price = $ 8.80 - $ 5.60 = $ 3.20
Now ratio of the decrease in price to the original price
$ 3.20 to $ 8.80
($ 3.20)/($ 8.80) = (3.20)/(8.80)= (3.20 × 100)/(8.80 × 100)= $\frac{320}{880}$= $\frac{320 ÷ 80}{880 ÷ 80}$= $\frac{4}{11}$
