Plot 1.5 and 71.9 on the number line to find which
inequalities are true. check all that apply.
< 1.5 < 1.5
< 1.9 < 1.9
< 1.5 < 1.9
1.2> 1.5 > 1.3
13< 1.9 < 1.4

astronomers is your final answer! : )

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
