The 9 times table

1*9 = 9

2*9 = 18

3*9 = 27

4*9 = 36

5*9 = 45

6*9 = 54

7*9 = 63

8*9 = 72

9*9 = 81

10*9 = 90

11*9 = 99

12*9 = 108

All the ones in bold are two digit numbers divisible by 9 because they are multiples of 9. THAT IS WHY YOU SHOULD LEARN YOUR TIMES TABLES!

What are the divisibility rules for 1 2 3 4 5 6 9 and 10?

All whole numbers are divisible by 1. Numbers are divisible by 2 if they end in 2, 4, 6, 8 or 0. Numbers are divisible by 3 if the sum of their digits is divisible by 3. Numbers are divisible by 4 if the last two digits of the number are divisible by 4. Numbers are divisible by 5 if the last digit of the number is either 5 or 0. Numbers are divisible by 6 if they are divisible by 2 and 3. Numbers are divisible by 9 if the sum of their digits is equal to 9 or a multiple of 9. Numbers are divisible by 10 if the last digit of the number is 0.


What is a 4 digit number that is divisible 3 and 9?

What numbers is divisible by both 9 and 4 5 digit?

A five-digit number that is divisible by both 9 and 4 must meet the criteria for divisibility by these numbers. A number is divisible by 9 if the sum of its digits is divisible by 9, and it is divisible by 4 if the last two digits form a number that is divisible by 4. The smallest five-digit number is 10,000, and the largest is 99,999; thus, any five-digit number that meets these criteria can be calculated by finding the least common multiple of 9 and 4, which is 36, and checking multiples of 36 within that range. For example, 10,008 is a five-digit number divisible by both 9 and 4.

How many 2-digit or 3-digit numbers can be formed using the digits 134568 and 9 which are diisible by 4?

48. Assuming no digit can be used more than once, the two digit numbers divisible by 4 are: 16, 36, 48, 56, 64, 68, 84, 96 8 of them. For any number to be divisible by 4, only the last two digits need be divisible by 4; so for three digit numbers, each of the two digit numbers above can be preceded by any of the remaining 5 digits and still be divisible by 4. → 5 x 8 = 40 three digit numbers are divisible by 4 → 40 + 8 = 48 two or three digit numbers made up of the digits {1, 3, 4, 5, 6, 8, 9} are divisible by 4. If repeats are allowed, there are an extra 2 two digit numbers (44 and 88) and each of the two digit numbers can be preceded by any of the 7 digits, making a total of 7 x 10 + 10 = 80 two and three digits numbers divisible by 4 make up of digits from the given set.

What are the greatest four digit numbers that are divisible by nine?

The greatest four-digit number is 9999. To find the largest four-digit number divisible by nine, we can check if 9999 is divisible by nine by summing its digits: 9 + 9 + 9 + 9 = 36, which is divisible by nine. Therefore, the greatest four-digit number that is divisible by nine is 9999 itself.
