No. The ratio of 3 and 6 is 1:2
Yes.
Yes.
Halfway between any two multiples of ten is always a multiple of five because each multiple of ten is also a multiple of five. For example, if you take the multiples of ten 20 and 30, their halfway point is 25, which is a multiple of five. This holds true for any pair of multiples of ten, as the average will always yield a number divisible by five.
YES 3+9=12 which is multiples of 3 30+3=33 which is multiple of 3 and so on..
Yes, the least common multiple is the product of the two numbers or the lowest number that both multiples can go into.
Any multiple of 10 is also a multiple of 2.
Any multiple of 8.
The common multiples of 9 and 16 are 144, 288, 432 and so on.
Any number can be a common multiple of two or more fractions. The concept of common multiples is useful only in the context of multiples of integers.
2
All nonzero numbers have multiples. Any two numbers will have an infinite number of multiples in common. The smallest of these is known as the least common multiple, or LCM.
Common multiples of 100 and 2 include any multiple of 100.
