An integer is simply a whole number (no fractions nor decimals).  It's an integer.

A rational number is one that can be written as a simple fraction: -17=-17/1.  It's a rational number.

A real number is any point on an infinitely long number line.  It's a real number.

-17 is an integer, a rational number, and real number

It's a whole number as well, since it's not a fraction or decimal. Answer is B.  Let me know if you have any questions :)

sooo..a whole number can be negative or positive? because i hear a whole is sometimes called a natural number which is positive integers and 0. now im confused:/

Hey, I apologize, some people consider negative numbers as whole numbers.  But I'm assuming this is what you're teacher taught you:

Whole numbers: 0,1,2,3,4,5......  So -17 would not be a whole number then.

Natural numbers: 1,2,3,4,5..... So -17 would not be a natural number then.

Integers: ....-2,-1,0,1,2.....

gotcha! so whole numbers are positive numbers AND 0? or is 0 not included?

Sep 14th, 2015

nevermind i see 0 is a whole but not natural, correct?

Sep 14th, 2015

Whole numbers are positive and include 0.  Natural numbers are positive and  do not include 0.
