is a multiple of. We know that

is a multiple of

, because

*3=

.
We can divide fractions to determine if

is a multiple of

:

;
in order to divide fractions, flip the second one and multiply:

)*

=

=1

.
This did not divide evenly, so

is not a multiple of 1/2.
Checking to see if

is a multiple of

,

;
flip the second one and multiply:

*

=

=6.
This divided evenly, so

is a multiple of

.
One way (among several) would be to add 700 and 300 in your head, and then add 44 and 4, also in your head, and then adding together these two sums.
700+300=?
44 + 4 = ?
