Question

At the local Media Mart, 4 out of every 65 people who visit the store will receive a free DVD. If 455 people visit the store, how many DVD’s will be given away?\

Answer 1

Here's the ratio:
4:61 (65 - 4 = 61)\
We can turn this into an equation:
65n =455
n = 91/13
We insert these numbers:
4*91/13:61*91/13
364/13: 5551/13
28: 427
28 DVDs will be given away.
