-30 belongs to what family of real numbers? A. Rational, Integer, Whole B. Rational, Integer, Whole, Counting C. Irrational D. Rational

OpenStudy (anonymous):

Real, Rational, Integer so out of the choices, A

OpenStudy (anonymous):

choice a its is

OpenStudy (anonymous):

@mrjoselson choice A. Rational, Integer, Whole is wrong because -30 is not a whole number

OpenStudy (anonymous):

same for choice B.

OpenStudy (anonymous):

D. Rational is the right choice as -30 can be written as -30/1 (p/q form)

OpenStudy (anonymous):

but you need to choose the answer that has the most correct answers. since non have Real, Rational, Integer, I selected the one that has two of them, not the one that only has one of them

OpenStudy (anonymous):

My understanding is that in a MCQ, you cannot choose an answer which is partly wrong. You have to choose an answer which is without doubt true.....☺

OpenStudy (anonymous):

A is without a doubt 100% true

OpenStudy (anonymous):

U mean to say that -30 is a whole number??

OpenStudy (anonymous):

I am sorry. I missed whole, you are correct

OpenStudy (anonymous):

I thought so because whenever I have seen yr answers r generally correct... but then we all make mistakes once in a while.... :)
