Which number is an integer, a rational number, and a real number?

–14
B.

C.
2/3

Answer 1

All Real. You don't see any \(i\) or \(j\) in there, do you?

All Rational
-14 = -14/1 <== Ratio of two integers!
0.1 = 1/10 <== Ratio of two integers!
2/3 <== Ratio of two integers with no alteration!
3.14 = 314/100 <== Ratio of two integers!

What do you think of integers? Any candidates?
