Michelangelo has 28 ceilings to paint. This week, he paints 12 of them. Next week, he will paint 1/4 the number of ceilings he did this week. How many ceilings will be left to paint after next week?
Let's think: After this week, Michelangelo will have 28 - 12 = 16 more ceilings to paint. Next week, Michelangelo will paint 12 / 4 = 3 ceilings. Michelangelo will have 16 - 3 = 13 more ceilings to paint.. The answer is: 13.

When Jane visited Iran, she visited 6 more than twice as many rehabilitation centers as Han. Han visited 2 less than twice as many rehabilitation centers as Jude did. Jude visited half fewer rehabilitation centers as Lisa did. If Lisa visited 6 rehabilitation centers, how many rehabilitation centers did they all visit assuming they are all different?
Let's think: Jude visited 1 / 2 * 6 = 3 rehabilitation centers. Han visited 2 * 3 - 2 = 4 rehabilitation centers. Jane visited 6 + 2 * 4 = 14 rehabilitation centers. They all visited 6 + 3 + 4 + 14 = 27 rehabilitation centers.. The answer is: 27.

Hershel has 10 betta fish and 15 goldfish in a bowl. His friend Bexley brings him 2/5 times as many betta fish and 1/3 times as many goldfish. If Hershel gifts his sister 1/2 of the fish, calculate the total number of fish he has remaining in the bowl.
Let's think: Bexley gives Hershel 2 / 5 * 10 = 4 betta fish. The total number of betta fish in the bowl is now 4 + 10 = 14. He also gives Hershel 1 / 3 * 15 = 5 goldfish. The total number of goldfish in the bowl is now 15 + 5 = 20. Counting the betta fish and goldfish, Hershel now has a total of 14 + 20 = 34 fish. When he gives his sister half of the fish, the remaining half is 34 / 2 = 17 fish.. The answer is: 17.

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?
Let's think:
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.. The answer is: 4500.
