is that divided?
myininaya (myininaya):
* means multiply
OpenStudy (anonymous):
ok so the answer would be no because it can be broken down in a simpler form
myininaya (myininaya):
i don't know what you are talking about, but the question is 5/x always less than 5 is false. A counterexample would be for x=0.1 since 5/(0.1)=5/(0.1)*(10/10)=50/1=50
and 50>5
myininaya (myininaya):
there are many different counterexamples
