Answer 1

ok 1st u have to know the definition of each
rational numbers are any of the numbers u are familiar with:
1,2,3... etc
irrational numbers contain i and
\[i=\sqrt{-1}\] its irrational because it cannot be done by normal rules
complex numbers contain part rational and part irrational so has a rational number and has an i in it

Answer 2

all are complex
first, second, third and fifth are rational
second and last are integers

Answer 3

excuse me i made a mistake. first, second, third and fifth are integers

Answer 4

unfortunately this line
"its irrational because it cannot be done by normal rules" is incorrect.

Answer 5

integers are
\[\{...,-3,-2,-1,0,1,2,3,...\}\]

Answer 6

I suppose rational is just integer/integer

Answer 7

Answer 8

rational number are of the form
\[\frac{a}{b}\] where a and b are integers and
\[b\neq 0\]

Answer 9

and a+ ib is complex...

Answer 10

any repeating or terminating decimal is rational

Answer 11

"irrational" means CANNOT be expressed in the form
\[\frac{a}{b}\]

Answer 12

REAL

Answer 13

Answer 15

and finally "COMPLEX" is any number of the form
\[a+bi\] where a and b are real and
\[i=\sqrt{-1}\]
