For a store contest four out of every sixtyfive people who visit the store will receive a free dvd. If 455 people visit the store how many DVDs were given away.
4/65 = x/455
Cross multiply and solve for x.
To find out how many DVDs were given away, we need to calculate the number of people who received a free DVD using the given ratio.
The ratio states that for every 65 people, 4 will receive a free DVD.
First, we need to calculate how many groups of 65 people are present in the total number of visitors:
455 ÷ 65 = 7
So, there are 7 groups of 65 people each.
Next, we need to determine how many DVDs were given away in each group:
7 groups × 4 DVDs per group = 28 DVDs
Therefore, 28 DVDs were given away.
