Melly's two cats each have litters of kittens at the same time. The first cat has 3 blue-eyed kittens and 7 brown-eyed kittens. The second cat has 4 blue-eyed kittens and 6 brown-eyed kittens. What percentage of all the kittens have blue eyes?
Thoughts? Step-by-step reasoning:
First find the total number of blue - eyed kittens: 3 kittens + 4 kittens = 7 kittens. Then find the total number of brown - eyed kittens: 7 kittens + 6 kittens = 13 kittens. Then add the number of each type of kitten to find the total number of kittens: 7 kittens + 13 kittens = 20 kittens. Then divide the number of blue - eyed kittens by the total number of kittens and multiply by 100% to express the answer as a percentage: 7 kittens / 20 kittens * 100% = 35%.
Thus, the answer is 35.
