If a number is a multiple of 2 and 3, it must be a multiple of 6______ ．
If a number is a multiple of 2 and 3, it must be a multiple of 6
A number is a multiple of 3 and 5 at the same time. What are the characteristics of this number?
The bits of this number are 0, 5: the sum of the bits and the tens equals 3 or a multiple of 3
The number with these two conditions is a multiple of 3.5
A number is a multiple of 2 and 3 at the same time. What are the characteristics of this number?
At the same time, a multiple of 2 or 3 is a multiple of 6
What are the characteristics of numbers that are multiples of 2 and 3 at the same time?
Also: what are the characteristics of numbers that are multiples of 2, 3 and 5 at the same time?
The last digit of a number that is a multiple of 2 and 3 is even, and the sum of each digit of this number is a multiple of 3
At the same time, the last digit of a number that is a multiple of 2, 3 and 5 is 0, and the sum of each digit of this number is a multiple of 3
A number is a multiple of 2.3 at the same time. What are the characteristics of this number
It's also a multiple of six
What are the characteristics of numbers that are multiples of 3 and 5 at the same time?
Number one: the sum of numbers is a multiple of three
Second: the single digit is 0 or 5
Numbers within 100 are multiples of both 5 and 7
5 * 7 = 35. At the same time, the end of 5 must be 5 or 10. In this way, the only one that meets the condition within 100 is
5*7=35 35*2=70
And so on, but because it is within 100, so only these two numbers hold!
Fill in 1, 1 / 8, 1 / 27 (), ()
64 and 125
Fill in the blanks 1, 2, 3, 4, 6, () and 12 according to the rules. It is said that it is a topic of kindergarten to primary school
It's difficult for our family
Possibility one:
1,2,3,4,6,(9),12
Rule: the divisor of 36 is arranged from small to large
Possibility two:
1,2,3,4,6,(8),12
Rule: the divisor of 24 is arranged from small to large
I don't seem to have learned approximate number in kindergarten
There's another possibility
1 2 3 4 6 (8) 12 find the rules and fill in the blanks
Single item 1 3 6 12
The last number of binomial 24 (8) = the first number × 2
Only binomial is regular
Figure 1 is a triangle. Connect the midpoint of the triangle to get Figure 2. Then connect the midpoint of the small triangle in the middle of Figure 2 to get Figure 3. Continue with this method. Please complete the following problem according to the rule of the number of triangles in each graph: in the nth graph, there are two triangles______ There are three triangles (represented by a formula containing n)
Count the number of triangles in Figure 1, figure 2 and figure 3 respectively, the number of triangles in Figure 1 is 4 × 1-3 = 1; the number of triangles in Figure 2 is 4 × 2-3 = 5; the number of triangles in Figure 3 is 4 × 3-3 = 9 It can be found that the number of triangles in the first graph is the product of 4 and several minus 3. According to this rule, if the number of graphs is n, then the number of triangles is 4n-3
