Taco Delight gives a free taco to every 12th customer and a free dessert to every 15th customer. Which customer would be the first one to receive both a free taco and a free dessert? Which customer would be the second one to receive a free taco and free desert?
the first person to get a free taco would be the 60th customer since 60 is a common multiple of both 12 and 15 and I believe the second would be 120th customer
