How many integers between 1 and 1000 inclusive are divisible by 6 or 21 but not by 7?
Oh, dude, let me break it down for you. So, first, you find how many numbers are divisible by 6, which is 166. Then you find how many are divisible by 21, which is 47. But wait, don't forget to subtract the ones divisible by both 6 and 21, which is 7. So, the total is 166 + 47 - 7 = 206 integers that fit the bill. Easy peasy!
What is the total number of prime numbers less than 100?
The total number of prime numbers less than 100 is 25.
Average of numbers?
To find the average of a given set of numbers, total the numbers and divide that total by the number of members of the set.
How test whether 58734 is divisible by 9?
Add up the digits. If the total is a multiple of 9, the whole number is a multiple of 9.
What is a number being added to another number?
Another number added to a number is the sum (total) of the two numbers.
Find total number of integers between 100 and 200 that are divisible by 3 and not divisible by 5 nor by 7?
There are 22 such numbers.
How many numbers between 20 to 50 are divisible by 3?
Oh, dude, let me break it down for you. So, we start at 21 because it's the first number between 20 and 50 that's divisible by 3, and then we just keep adding 3 until we hit 48. So, that gives us 10 numbers in total. Easy peasy, right?
How can we Describe a rule for deciding if a number is divisible by three consider numbers greater than 1000?
The rule for deciding if a number is divisible by 3 is to add up the digits of the number. If that total is a multiple of 3, the original number is as well. This applies to numbers of any length.
What is the smallest digit that can be placed in the blank so that 67 and 45 is divisible by 3?
Let's assume, or hope, that the blank is after those numbers. 67_ and 45_ For a number to be divisible by three, the total of the number's digits has to be divisible by three. 672 and 450
All numbers that are divisible by 6?
All numbers that are divisible by 6 are even numbers whose digits add up to 3 or a multiple of 3. Example : 284 is not wholly divisible by 6 as although it is even, its digits total 2 + 8 + 4 = 14 which is not divisible by 3. 282 is divisible by 6 as it is even and its digits total 12 which is divisible by 3.
How many numbers between 0 100 are divisible by 7?
There are a total of 14 numbers between 0 & 100 that are divisible by 7.
Is 164 a multiple of 3?
No. (A short cut to check if a number is divisible by 3. Add all the numbers and if the total divides by 3, then the number will divide by 3. eg 1+6+4 =11, which is not divisible by 3 therefore 164 is not divisible by 3)
What numbers can you divide evenly by 9?
Any multiple of 9. In other words, any number of the form 9 * n. Add the digits of the number. If that total is divisible by nine, so is the original number. Example: 12,345,678. The digits total 36. 36 is divisible by 9. So is 12,345,678.
What is the total number of integers between 100 and 300 that are divisible by 3?
To find the total number of integers between 100 and 300 that are divisible by 3, we first determine the smallest and largest integers in this range that are divisible by 3. The smallest integer divisible by 3 is 102, and the largest is 297. To find the total number of integers between 102 and 297 that are divisible by 3, we calculate (297-102)/3 + 1, which equals 66. Therefore, there are 66 integers between 100 and 300 that are divisible by 3.
What is the divisibility rule of 3?
all digits in the number must total to a number divisible by 3 when added up e.g 156=1+5+6=12 which is divisible by 3 you can proove this using other numbers eg 39,24,1107 e.t.c
How do you know if the number is divisible by 15?
All numbers divisible by 5 (of which 15 is a multiple) have a final digit of 0 or 5. All numbers divisible by 3 (of which 15 is a multiple) have the sum of the digits totalling 3 or a multiple of 3. Therefore, a number is divisible by 15 if the sum of its digits total 3 or a multiple of 3 and its final digit is 0 or 5. Example : 32085 ; 3 + 2 + 0 + 8 + 5 = 18 which is divisible by 3. Final digit 5. This number is divisible by 15. (32085 ÷ 15 = 2139) 7420 : 7 + 4 + 2 + 0 = 13. This number is not divisible by 15.
Is the total number of natural numbers same as the total number of prime numbers?
No.
