In a day a movie store rented out 50 comedies.
The ratio of comedies rented to action movies was 10:7
How many action movies were rented?
Let the number of action movies rented be x
[tex]\frac{50}{x}[/tex] = [tex]\frac{10}{7}[/tex]
Cross multiplying gives
350 = 10x , x = 350/10
x = 35
So there were 35 action movies rented.
