Answer:
You have 0 friends just like me :D
Let's put it into numbers:
Ruba: 1 000 000
Zamba: 100 000 000 000
Zamba has many more aliens than Ruba!!!
it has 100 000 000 000/1 000 000 =100 000 times more aliens,
in absolute numbers: 100 000 000 000 - 1000 000 = =99 999 900 000
100 000 000 000
- 100 000
=99 999 900 000
For the 8 inch pie you are paying about 55 cents per inch
for the 10 inch pie you are paying about 61 cents per inch
so the 8 inch pie is a better deal
hope this helped
oh and to get those numbers divide 4.39 by 8 and 6.15 by 10
