There are two ways to solve this problem.
A.
Change both metric numbers to a common metric term, such as 3000K
+ 4K.
B.
Change both metric numbers to their base equivalents, 3,000,000 +
4,000.
Since you already know how to do B, in this text we will use ________.

Two
fractions
are
equivalent
if
both
can
be
reduced
to
the
same
fraction.
For example, 1/3 = 15/45 because 15/45 can be reduced to 1/3 by
dividing both numerator and denominator by 15.
Is it true that 4/10 = 12/30?
