How many multiples of 7 are odd numbers?
odd multiples of 7 are odd numbers.. like 7*1, 7*3,7*5..
Are all of the multiples of 7 odd?
No, try 14.
Why are all multiples of 3 odd and even?
The multiples of all odd numbers are odd and even. Odd x odd = odd. Odd x even = even. Since odd and even numbers alternate, the multiples will alternate as well.
What are all the odd numbers up to 5000 that are multiples of 4?
No odd numbers are multiples of 4.
What are the odd multiples of 5?
Itself and any of its multiples that ends with a 5
How many multiples of 7 are odd numbers?
odd multiples of 7 are odd numbers.. like 7*1, 7*3,7*5..
What are the common multiples of 3 7 but not 6?
Odd multiples of 21.
Are all of the multiples of 7 odd?
No, try 14.
The first three odd common multiples of 7 and 9?
63
What are odd multiples of 7 less than fifty 50?
7, 21, 35, 49
Why are all multiples of 3 odd and even?
The multiples of all odd numbers are odd and even. Odd x odd = odd. Odd x even = even. Since odd and even numbers alternate, the multiples will alternate as well.
Between 1 and 100 how many multiples of 7 are odd numbers?
Start out looking at them. 7x1=7 odd 7x2=14 even 7x3=21 odd 7x4=28 even 7x5=35 odd 7x6=42 even... so it looks like half might be even and half odd, This is because if we look at the numbers 1-14, ie 1,2,3,4,5,6,7,8,9,10,11,12,13. and 14, they alternate odd and even and since 7 is odd and odd times an even is always an even number and an odd times an odd is always an odd number. So to answer the question we need only look at the number of odd numbers between 1 and 14 inclusive. There are 6 so 1,3,5,7,9,11,13 give odd multiples ANSWER: so 7 odd multiples of 7 between 1 and 100
Does all of the multiples of 7 have 2 as a factor too?
For 2 to be a factor, the number has to be even. If you multiply two odd numbers together, you get an odd number. 7 is odd, so if I multiply it by any odd number, I will get a number that doesn't have 2 as a factor (e.g. 7x5=35 which doesn't have 2 as a factor). Thus, the answer to the question is "no," not all multiples of 7 have 2 as a factor.
Are all multiples of 3 odd?
No - alternate multiples of 3 are odd, and alternate multiples are even.
What odd number is divisible by 7 and is the sum of two and is less than 25 consecutive numbers?
All odd numbers are the sum of two consecutive numbers. Odd multiples of 7 less than 25 are 7 and 21.
What are all the odd numbers up to 5000 that are multiples of 4?
No odd numbers are multiples of 4.
Why aren't all odd numbers divisible by 3?
Because not all odd numbers are multiples of 3 - I have shown you below that this is the case and you can see some multiples of 3 are even and some are odd and you can also see that there are even and odd numbers BETWEEN the multiples of 3. 1 (odd) 2 (even) 1*3 =3 (odd) 4 (even) 5 (odd) 2*3 = 6 (even) 7 (odd) 8 (even) 3*3 = 9 (odd) 10 (even) 11 (odd) 4*3 = 12 (even)
