Divide 18 fish into several parts equally, and there is no surplus. How many ways do you divide it? There are six kinds: each serving 18 fish, each serving 1 fish; 9 points each, 2 points; 6 copies each, divided into 3 copies; 3 copies each, divided into 6 copies; 2 copies each, divided into 9 copies; Each copy is 1 and the score is 18.

30 apples are divided into several parts equally, and no surplus is allowed. How many ways do you divide them? Ok, I'll say it according to the number of each serving.

A copy of 1

A copy of 2.

A copy of 3.

A five.

A six.

A copy of 10

Copy of 15.

I only have seven kinds, please give me the best answer!

Divide the 24 apples into several parts equally, and there is no surplus. How many kinds of distribution do you have? 2× 12, 3×8, 4×6, 6×4, 8×3, 12×2.

There are 18 apples divided into several parts equally, and no surplus is allowed. You have several methods. 18 apples are divided into several parts on average, and there are six ways to divide them into 1, 2, 3, 6, 9 and 18.

Divide 18 apples into several points on average, and there is no surplus. What's your score? Write 1, 2,3,6,9, 18.

There are several ways to divide 24 story books into several parts: 24/ 1 = 24.

24/2= 12

24/3=8

24/4=6

24/6=4

24/8=3

24/ 12=2

24/24= 1

Math problem in the fifth grade: Divide the 24 story books into several parts, with no surplus, and some parts are relatively simple: one, 24, one, 1, one, two, 12, one, two, one, three, eight and one.

144 oranges are divided into several portions on average, and each portion is not less than 10 oranges. How many ways are there? Equivalent to 2*2*2*2*3*3.

If you use permutation and combination (I can't type that symbol, I can only give you a vague calculation, I don't know if you can understand it), first calculate the number of times less than 10: it is equivalent to choosing12 3 4 from 4 2, and the number 3 is the same.

There is (4+6+4+1) * (2+1) = 30 (if you have studied permutation and combination, you should be able to understand it, right? )

Subtracting the number less than 10 is equivalent to subtracting six cases where each part is 2/3/4/6/8/9 (that is, the product of 2/3 is less than 10).

In this way, the result should be about 24!

You really can't count one by one. There are only 24 kinds. I think so!

48 oranges are required to be divided into several parts equally, and no surplus is allowed. How many ways are there? 1.48; 2.24; 3. 16; 4. 12; 6.8; 8.6; 12.4; 16.3; 24.2; 48. 1
