Two of the dozen eggs in a carton are cracked. about what percent of the carton are not cracked?

Okay, so 2 of 12 eggs are cracked, which means that 10 out of 12 eggs are not cracked. We will use number ten to figure this out. Here is how to do it:
10 : 12 = x : 100%
12x = 10*100
12x = 1000
x = 1000/12
x = 83.33

This means that about 83% of the eggs in the carton are not cracked.
