In proportion, two external terms are reciprocal to each other. One internal term is 7 and the other internal term is 7
The inward product is equal to the outward product, so the answer is 1 / 7
Use the numbers 123456789 to form a four digit number and multiply it by a one digit number, which is exactly equal to a four digit number
1738*4=6952
1963*4=7852
I want to know what is the least common multiple of 1 2 3 4 5 6 7 8 9?
The calculation method is as follows: first step 1 = 12 = 23 = 34 = 2 * 25 = 56 = 2 * 37 = 78 = 2 * 2 * 29 = 3 * 3 second step: least common multiple = 1 * 2 * 2 * 2 * 3 * 3 * 5 * 7 = 2520
A number is not only a multiple of 2, but also a multiple of 12. It can be divisible by 14. The minimum number is
It's the least common multiple of 2, 12 and 14
A number can be divided by 2.3.5 at the same time. This number must be a multiple of 30, right?
Urgent need
2.3.5 the least common multiple is 30, right
A number is not only a multiple of 6, but also a multiple of 9______ ．
Because 6 = 2 × 3, 9 = 3 × 3, the least common multiple of 6 and 9 is: 2 × 3 × 3 = 18, so the answer is: 18
A three digit number can be divided by two and three, and the number of one digit and ten digit are the same. The maximum number of the three digit number is two______ ．
8 + 8 + = 24, 24 ÷ 3 = 8, therefore, 888, a three digit number, can be divided by both 2 and 3, and the individual and ten digits are the same; therefore, the answer is: 888
What are the characteristics of numbers divisible by 9?
The sum of all digits of a number divisible by 3 must be a multiple of 3, and 9 is a multiple of 3, so the sum of all digits of a number divisible by 9 is a multiple of 9
What are the characteristics of numbers divisible by 9
The sum of the digits can be divided by 9
