[Question]: Billy is counting the rings in two trees. Weather fluctuations in this area mean that each tree's rings are in groups of two fat rings and four thin rings. If Billy counts 70 ring groups in the first tree and 40 ring groups in the second tree, how much older is the first tree? (Trees grow 1 ring per year.)
[Answer]: First find the total number of rings in a ring group: 2 rings + 4 rings = 6 rings. Then subtract the number of ring groups in the second tree from the number in the first tree to find the difference: 70 groups - 40 groups = 30 groups. Then multiply that number by the number of rings in a group to find the difference in the trees' ages: 30 groups * 6 rings / group = 180 rings, or 180 years.
So the answer is 180.

[Question]: There were 25 peaches in each basket. Five baskets of peaches were delivered to a market. The farmers have eaten 5 peaches. The remaining peaches are packed into smaller boxes of 15 each. How many boxes of peaches are there?
[Answer]: The total number of peaches delivered to a market was 5 x 25 = 125. The remaining peaches after 5 were eaten was 150 - 5 = 145. So, there are 120 / 15 = 8 smaller boxes of peaches.
So the answer is 8.

[Question]: Maya loves to read books. Last week she read 5 books. Each book had 300 pages of text. This week she read twice as much. How many pages did Maya read in total?
[Answer]:
Last week Maya read 5 * 300 = 1500 pages of text. This week she doubled the result, so she read 2 * 1500 = 3000 pages. In total Maya read 1500 + 3000 = 4500 pages of text.
So the answer is 4500.
