An odd number plus an odd number is what kind of number?
An odd number plus an odd number will be an even number. Odd number A is (even number + 1) Odd number B is (even number + 1) A + B = (even number + 1) + (even number + 1) = even number + even number + 2 Since all even numbers are divisible by 2 and 2 is divisible by 2, each part of the result is divisible by 2, so the sum as a whole is divisible by 2, which means it is an even number.
Why any number that is divisible by 9 is also divisible by 3?
as 9 is made of 3 times 3 so any number (such as 90) which is divisible by 9 will also be divisible by 3 and the answer will be 3 times bigger so 90/9 is 10 then 90/3 = 30 which is 10 x 3 Example: same for any number that is divisible by 14 will also be divisible by 7 (or also 2) as 14 = 7 x 2 or divisible by say 50 is also divisible by 5 or 10 as 50 = 5 x 10 and so on ...
Are all numbers that are divisible by 5 are also divisible by 10?
Yes, all numbers that are divisible by 5 are also divisible by 10. This is because 10 is a multiple of 5. When we say that a number is divisible by 5, we mean that it can be evenly divided by 5 with no remainder. When we say that a number is divisible by 10, we mean that it can be evenly
What can you conclude if a and b are nonzero integers such that a divisible by b and b divisible by a?
That a = ±b
What does divisible by mean?
If 'A' is 'divisible by 'B', it means that: -- If 'B' is repeatedly subtracted from 'A', then the last one fits exactly, without anything left over -- 'A' was made by piling up some whole number of 'B's, with no extras -- 'B' goes into 'A' evenly --'A'/'B'= some whole number
What are the factors of 312 using the divisibility rule?
312 is divisible by 2 b/c the 2 at the end of 312 is an even number312 is divisible by 3 b/c 3 + 1 + 2 = 6 which is divisible by 3312 is divisible by 4 b/c 12 is divisible by 4312 is not divisible by 5 b/c the one's place isn't 0 or 5312 is divisible by 6 b/c 312 is divisible by 2 and 3312 is not divisible by 7 b/c 2*7=14, 31-14=17 which is not divisible by 7312 is divisible by 8 b/c 312/8=39 (Explanation: A way to find out how 8 is divisible its that its first three digits [the ones, tens, and hundreds place] have to be divisible by 8)312 is not divisible by 9 b/c 3 + 1 + 2 = 6 which is not divisible by 9312 is not divisible by 10 b/c the ones place is not 0
When four digit number A 5 5 B is divisible by 36 What is the sum of A and B?
To be divisible by 36 the number must be divisible by 9 (and 4). To be divisible by 9, the sum of the digits must be divisible by 9. 5 + 5 = 10 → need an extra 8 → A + B = 8.
Is 2 divisible by 7623?
Remark: For any two numbers a and b, b never divides a exactly if b is greater than a.So, 2 is not divisible by 7623.
What is B divisible by?
At least B and 1. There may be others depending on the value of B.
Does not even that mean more or less then?
Ok, we are talking logical terms Less than is A < B ie A is less than B ie A can be 4 and B is anything less than 4 ie 3 or less Greater than is the opposite A>B so A can be 4 again and B has to be 5 or more. Not even can mean two things, you dont really say it like that Not even, ie even and odd, so you have even numbers, divisible by 2 ie 2 4 6 8 10 etc and odd numbers, which are not divisible by 2 ie 1 3 5 7 9 etc Not even could be that it is not divisible by two. OR if you mean not equal since we were talking about greater and less than, then it means one number is not equal to another ie A /=B would mean that A is ANY number other than what was assigned to B ie A could be 4 and B is anything BUT 4, ie 5, 20, 102131 would be good. Got it?
What is the GCF of 29 and 87?
GCF of a and b is a if b is divisible by a.87 is divisible by 29 so, GCF(29,87) = 29.
When is a three digit number divisible by eleven?
Let A, B, C are digits. Number ABC is divisible by eleven if and only if A+C-B=0 or A+C-B=11
What is the LCM for 12 2?
If a is divisible by b, then LCM of a and b is a.Here 12 is divisible by 2. So, LCM of 2 and 12 is 12.
Is 1 divisible by 2?
No.A number a is divisible by another number b, if and only if the fraction a/b is equivalent to a whole number. And as you know, 1/2 = 0.5, which is not a whole number, hence is 1 not divisible by 2.The only number 1 is divisible by, is 1 itself. All numbers are divisible by 1.
