Step-by-step explanation:
Given : The movie house gives away a 5$ coupon for every 4 movies purchased they give away a bag of popcorn for every 3 movies purchased.
To find : How many movies would you have to purchase in all before receiving both ?
Solution :

For every 4 movies purchased,
The multiples of 4 are 4, 8, 12
For every 3 movies purchased,
The multiples of 3 are 3, 6, 9, 12
LCM (3,4) = 12
