2. (false) Every integer is a rational number. ---- nope, I can put every integer over 1 to make it
look like a natural number. e.g. -6 = -6/1 or -12/2

(false) Every Rational number is a whole number. I agree

(true) Every natural number is a whole number. whole numbers are 0,1,2,... natural numbers
exclude the 0, so it is false

(true) 3 is an element of the rational numbers. I agree, we can write 3 as 6/2
