you said numbers that go on forever don't make sense
I said all numbers go on forever. for example 1.000... = 1
OpenStudy (anonymous):
ok
OpenStudy (skullpatrol):
so we need a definition of an "irrational number", right?
OpenStudy (anonymous):
yes
OpenStudy (skullpatrol):
do you know what a "rational number" is defined as?

the ratio of two numbers i think
OpenStudy (skullpatrol):
very good, so an irrational number can not be expressed as a ratio of two integers
OpenStudy (anonymous):
so is it c?
OpenStudy (anonymous):
bcuz that's only one integer
OpenStudy (skullpatrol):
yes
