Task 1: Finding the Whole and Fractional Parts of Fractions

To find the whole and fractional parts of each fraction, let's go through each fraction one by one:

1. 37/35: - The whole part is 1 because 37 divided by 35 equals 1 with a remainder of 2. - The fractional part is 2/35.

2. 18/5: - The whole part is 3 because 18 divided by 5 equals 3 with a remainder of 3. - The fractional part is 3/5.

3. 28/7: - The whole part is 4 because 28 divided by 7 equals 4 with no remainder. - The fractional part is 0/7, which simplifies to 0.

4. 56/28: - The whole part is 2 because 56 divided by 28 equals 2 with no remainder. - The fractional part is 0/28, which simplifies to 0.

5. 11/3: - The whole part is 3 because 11 divided by 3 equals 3 with a remainder of 2. - The fractional part is 2/3.

6. 9/2: - The whole part is 4 because 9 divided by 2 equals 4 with a remainder of 1. - The fractional part is 1/2.

Task 2: Length of Remaining Rope

Let's calculate the length of the remaining rope after cutting off two pieces:

1. The first piece is 4/13 of the total length of the rope. - To find this length, multiply 4/13 by the total length of the rope, which is 26 meters. - (4/13) * 26 = 8 meters.

2. The second piece is 2/13 of the total length of the rope. - To find this length, multiply 2/13 by the remaining length of the rope after the first cut. - The remaining length of the rope is 26 - 8 = 18 meters. - (2/13) * 18 = 2.769 meters (rounded to three decimal places).

Therefore, the length of the rope that remains after the two cuts is approximately 2.769 meters.

Task 3: Number of Books about Plants and Animals

Let's determine the number of books about plants and animals in the school library:

1. There are 360 children's books in total. 2. 2/15 of the books are about fairy tales. - To find the number of books about fairy tales, multiply 2/15 by 360. - (2/15) * 360 = 48 books.

3. 1/15 of the books are poetry collections. - To find the number of poetry collections, multiply 1/15 by 360. - (1/15) * 360 = 24 books.

4. 4/15 of the books are about travel. - To find the number of books about travel, multiply 4/15 by 360. - (4/15) * 360 = 96 books.

5. The remaining books are about plants and animals. - To find the number of books about plants and animals, subtract the sum of books about fairy tales, poetry collections, and travel from the total number of children's books. - 360 - (48 + 24 + 96) = 192 books.

Therefore, there are 192 books about plants and animals in the school library.
