If Ann and Cate ate 75% of their pizzas, then they each ate 75/100 * 4 = 3 pieces.
If Bill and Dale consumed 50% of their pizzas, then they each ate 50/100 * 4 = 2 pieces.
So, Ann and Cate together ate 3 + 3 = 6 pieces.
And Bill and Dale together ate 2 + 2 = 4 pieces.
If each pizza is divided into 4 pieces, then there are a total of 4 x 4 = 16 pieces.
Therefore, there are 16 - 6 - 4 = 6 pieces remaining uneaten.
#### 6
