Grade 5

I’m thinking of a number written with five digits. It’s a decimal between 26 and 27, and it has only even digits. All its digits are different.

- The first two digits of the number are 2 and 6. Many numbers are possible.
- The smallest number is 26.048.
- Other numbers are 26.084, 26.408, 26.480, 26.804, and 26.840. These six numbers differ only by the order of the digits after the decimal point.

Eight books fit in a box. If there are 28 books, how many boxes will be filled? Ignore the remainder, because the question asks about full boxes. If you just change the question to, “How many boxes will be used?” you can include the remainder as a fraction, so the answer will be 3.
