[Question]: Three baskets A, B and C contain different numbers of differently colored marbles. Basket A contains 4 red marbles and 2 yellow marbles. Basket B contains 6 green marbles and 1 yellow marble. Basket C contains 3 white marbles and 9 yellow marbles. What is the difference between the number of each color of marble in the basket that has the greatest difference?
[Answer]: In basket A the number difference between differently colored marbles is 4 - 2 = 2. In basket B the difference is 6 - 1 = 5. In basket C the difference is 9 - 3 = 6. Comparing 2, 5 and 6 shows that 6 is the greatest difference.
So the answer is 6.

[Question]: 5 geckos on the kitchen window eat 6 insects each. 3 lizards eat twice as much as the geckos. How many total insects were eaten?
[Answer]: The number of insects the geckos eat is 5 x 6 = 30. The number of insects the lizards eat is 3 x 12 = 36. The total number of insects eaten is 30 + 36 = 66 insects.
So the answer is 66.

[Question]: The town of Belize has 400 homes. One fourth of the town's homes are white. One fifth of the non-white homes have a fireplace. How many of the non-white homes do not have a fireplace?
[Answer]:
There are 400 / 4 = 100 white homes in Belize. There are 400 - 100 = 300 non - white homes in Belize. There are 300 / 5 = 60 non - white homes that have a fireplace. There are 300 - 60 = 240 non - white homes that do not have a fireplace.
So the answer is 240.
