At her health club, Lauren uses a treadmill every 2 days and the weight
machines every 8 days. She used a
treadmill on March 2 and will use
the weight machines on March 8.
Lauren says that the first time she
will use both a treadmill and the
weight machines in March is March 16
because the LCM of 2 and 8 is 16.
Does Lauren's reasoning make sense?
