It is known that both the internal and external terms of a proportion are natural numbers, and the product of the two external terms is 30. What are the two internal terms

Inner term product = outer term product = 30
30＝1x30=2x15=3x10=5x6
So there are two ratios:
1:5=6:30
2:3=10:15
A: the two items may be 5 and 6, 3 and 10 respectively

In proportion, the ratio of the product of two external terms to the product of two internal terms is 1:1
judge
Right or wrong

Yes
In proportion, the product of two external terms is equal to the product of two internal terms, and the ratio of the two products is of course 1:1
For example: 2:3 = 4:6
Here, 2x6 = 12, 3x4 = 12, 12:12 = 1:1

In proportion, the product of two inner terms equals the product of two outer terms
If it's not in the same proportion, is that right?

No,
In proportion, the product of two inner terms equals the product of two outer terms
It means in the same proportion

A number is a multiple of 3 and can be divided by 6, but there is no factor 2. What is the number?

In other words, "it's a divisor of 6 and a multiple of 3, but it's not a multiple of 2". It's easy to understand that this number is 3

There is a number, it is a multiple of 3, 6 is a multiple of this number, but it has no factor 2, this number is

Hello, and glad to meet you
There's a number, it's a multiple of 3, 6 is a multiple of this number, but it doesn't have a factor of 2
This number is [3]
3 is a multiple of 3
6 is a multiple of 3
3 has no factor 2

A number is not only a factor of 100, but also a multiple of 10. It can't be divided by 4. What's the number

10,50

A number is a factor of 100 and a multiple of 10. It cannot be divided by 4. Find the number and write the reason

A number is a factor of 100 and a multiple of 10
It could be 10 20 50 100
It's not divisible by four, so it's 10 or 50

At the same time: it is a factor of 100 and a multiple of 10, but not a multiple of 4

2、5、10、50、、25

There is a number that is a factor of 100 and a multiple of 10, but not a multiple of 4 and smaller than 25. This number is ()

It's a multiple of 10, which is the number of the whole 10
It's smaller than 25, so it's only 20 10
It can't be a multiple of 4, so it can only be 10

What is the least common multiple of 1,2,3,4,5,6,7,8,9,10?
Is there any necessary connection between this and a circle divided into 360 degrees?

It's 5 * 7 * 8 * 9 = 2520
It doesn't seem to matter that the circle is divided into 360 degrees
