To make this equation easier, we can just divide the data by 2, so that the exact number of eggs that survived, is the percentage that survived.
Explanation:
200 = 200 Total Eggs
136 = 136 Eggs That Broke
So, the ratio of eggs that broke to total eggs is:
136 / 200
So, subtract the number of eggs that broke to the total eggs, to find the amount that survived.
200 - 136 = 64
So now we know that, 64 eggs of 200 survived.
Which means, that 32% off the eggs had survived.
