Are multiples of 100 also multiples of 200?

Answer 1

Half of multiples of 100 are also multiples of 200. The odd multiples of 100 (300, 500, 700, 900, ...) are not whole multiples of 200.

To be precise, we are talking about whole # multiples! For example, 300 is a whole # multiple of 100 (100 x 3)...but is also a multiple of 200, just not a whole # multiple (200 x 1.5)

Realistically, any # that ends in 00 is a whole number multiple of 100. ex 100,200,300,400,500,...999,900...

Any # that ends in an even # followed by 00, is also a whole number multiple of 200. ex 200,400,600,800,...
