Is 4339 divisible by 3?
No. To find if a number is a factor of 3, add the number's digits. If the resulting number is a multiple of 3, then the original number is a multiple of 3. In 4339, the digits of the number added together is 19, which is not a multiple of 3.

Is 342 divisible by 5 or 6?
342 is divisible by 6 and not 5.Numbers divisible by 5 end in zeros or fivesNumbers divisible by 6 have a slightly more complicated rule. If, when the individual digits are added together and they make a multiple of 3, see if the number is even. If so, and the digits add up to a multiple of 3, then the number is a divisible by 6.

Why is it when a number between 1 to 8 when multiplied to 3 added to 3 multiplied by 3 and added together always ends up as 9?
First, let's see what calculation you are doing. Let your number 1-8 be n. Then the calcultion is: Multiply by 3: 3n Add 3: 3n + 3 Multiply by 3: 3(3n + 3) So your steps change n into 3(3n + 3) Expanding and rearranging 3(3n + 3) gives: 3(3n + 3) = 9n + 9 = 9(n + 1) So the final number will be a multiple of 9. To check whether a number is a multiple of 9 or not, add its digits together and if the result is a multiple of 9, then the original number must be a multiple of 9. Thus the digits of the result of the calculation must add together to a multiple of 9, namely 9, 18, 27, etc. As your initial number is 1 to 8, the result of the calculation will have 2 digits and be less than 90; the sum of the 2 digits must be a multiple of 9 and so will be 9.
Is 5715 divisible by 2 3 5 9 or 10?
5715 is not divisible by 2: the last digit is not an even number or 05715 is divisible by 3: as the last two digits when added together is a multiple of 35715 is divisible by 5: as the last digit is a 5 or 05715 is divisible by 9: as if u added all the digits of the number it will be divisible by 9, in this case 5 +7+1+5=18 and 18 is a multiple of 95715 is not divisible by 10: as the last digit is not a 0
Why is the answer always a whole number when the sum of two digits under 10 are added together?
This follows from the property that the set of integers is closed under addition. This means that any two integers, when added together, must always result in a whole number.
A two digit number is five times the sum of the digits if 9 is added to the number the digits are reversed find the number?

How do you do an average on a math paper?
add all the numbers together. 10,12,15,13=40 then divide by the number of digits you added together. 40 divided by 4 is 10 the average is 10
