Bill has 5/8 of his pizzas in the fridge. He eats 1/4 of the pizzas for breakfast. Then, he puts 3/8 of the pizzas in the freezer. How many pizzas does he have left in the fridge?
The number of pizzas in the fridge is 5/8 * 8 = <<5/8*8=5>>5 pizzas.
He eats 1/4 * 5 = <<1/4*5=1.25>>1.25 pizzas.
He puts 3/8 * 5 = <<3/8*5=1.875>>1.875 pizzas in the freezer.
So, he has 5 - 1.25 - 1.875 = <<5-1.25-1.875=1.875>>1.875 pizzas left in the fridge. Answer: \boxed{1.875}.
