In 2014, the global circulation of
National Geographic was about
6.8 million magazines. In that same year, Time had a
global circulation of about 3.3 million magazines. What was the difference between the
global circulations of the two magazines?
First, we’re given the global
circulation of National Geographic. It is 6.8 million. The global circulation of Time
magazine is 3.3 million. And we’re looking for the
difference. The difference means we need to
subtract. We need to subtract the 3.3 million
magazines that Time magazine circulated from the 6.8 million that National
Geographic circulated.
We’re now going to subtract with
decimals. Starting all the way on the right,
we’ll take three from eight. Eight minus three is five. What should we do with our decimal
place? Bring it down exactly where it was
in line. And from there, we take six minus
three, which equals three. This gives us a difference of
3.5.
Not just 3.5 though, we have to
remember our units. The difference in circulation was
3.5 million. National Geographic’s global
circulation was 3.5 million more than Time magazine.
