Question

1. is 0.5 a rational number?
2. is 0 a rational number?
3. is the power of 169 a natural number?
4. is 200% a whole number?
5. is 7/2 a integer?
6. is a rational number also a integer?
7. is a whole number number also a irrational number?

im in seventh grade honors

Answer 1

1. of course, it is 1/2
2. yes, 0 is a number
3. not sure what you mean; square root of 169 would be 13, so that would be natural, if that is what you mean
4. 200% = 2 or double, so yes
5. no, 7/2 = 3.5, not an integer
6. all integers are rational, but not all rationals are integers; make sense??
7. all whole numbers are rational, so no; not sure what a whole number number means

Answer 2

Natural numbers : 1,2,3,...
Integers : naturals + "negative naturals' + 0
Rational numbers : Integers and fractions
Irrational numbers : Rational numbers + all other numbers ( square root 2, PI )

whole numbers are same as integers

1) yes, 0.5 = 1/2 a fraction
2 yes an integer
3 yes 169 * 169 an integer
4 yes 200 % ( unless it is 200% of some value )
5 no 7/2 is a fraction
6 no no not always, 2/3 is a fraction thus a rational but it is not an integer.
7 no/yes , well a whole number is part of the set of irrationals, but a whole number is also a rational number and an integer

Answer 3

Wow..sounds exactly like what I'm doing in 8th grade Honors...ok here goes..blame urself for taking my answers if u get them wrong.(I'm in 8th remember)..ok...

1. yes.
2. no.not positive or negative
3. i would think 13 is
4. no because it is not a # is is a %...a whole # doesnt have any decimals liek 12 is and 12.7 isnt...get it?
5. any # can be an integer because a # line is infinant either way(negative and positive) so yes.
6. yea( if you haven't gotten it from the other answers)
7. i dont get the question..SoSry.

BTW..wat grade are you in that an 8th grader has 2 answer ur math HW?????
