Final answer:
By maintaining the 1:2 ratio of black kittens to total kittens that Anna has, we can calculate that Kevin should have 5 black kittens out of his total of 10 kittens.
Step-by-step explanation:
The question involves finding out how many of Kevin's kittens are black based on the same ratio that Anna has with her kittens. Anna has four kittens in total, with two of them being black. Therefore, the ratio of black kittens to total kittens for Anna is 2 black kittens out of 4 total kittens, which simplifies to 1:2 (for every one black kitten, there are two total kittens).
Given that Kevin has 10 kittens in total and assuming he has the same ratio as Anna's, we want to maintain the 1:2 ratio. To find out how many of Kevin's kittens are black, we simply need to divide his total number of kittens by 2:
- Black kittens of Kevin = Total kittens of Kevin / 2
- Black kittens of Kevin = 10 / 2
- Black kittens of Kevin = 5
