Question

for a store contest four out of every 65 people who visit the store will receive a free DVD if 455 people visit the store how many DVDs were given away?

Answer 1

If the rate at which they are giving the DVDs is the same then it is 4/65 or 16.25% or 0.1625.

Now just multiply 455 by the rate (4/65 or 16.25% or 0.1625) to find how many DVDs were given.

455 × (4/65) = 28

28 DVDs were given away

hope it helps :)
