To solve this, let’s find the smallest common multiple of the slice counts for each pizza type (8 slices for cheese and 4 slices for pepperoni), because we need an equal number of slices for both.

1. Identify the slice counts per pizza type:

   • Cheese pizza: 8 slices.
   • Pepperoni pizza: 4 slices.

2. Find the Least Common Multiple (LCM):

   • The LCM of 8 and 4 is 8, as 8 is the smallest number divisible by both 8 and 4.

3. Determine the number of slices sold:

   • Since 8 is the LCM, the restaurant must have sold at least 8 slices of each type to have an equal number of slices.

Thus, the smallest number of slices of each type that the restaurant must have sold is 8 slices.
