Choose all sets that contain the number 5. natural numbers whole numbers integers rational numbers irrational numbers real numbers

You'll want to be familiar with the definitions of each of the answer choices:
natural numbers are positive integers (so 1, 2, 3, etc)
whole numbers are just numbers without fractions (so, any integer)
integers are whole numbers, positive or negative
rational numbers can be written as a ratio (a fraction)
irrational numbers CAN'T be written as a ratio (so, like pi)
real numbers include all rational and irrational numbers

so, you see that a lot of these overlap. go through them and see what the number 5 can apply to. yes, it's a positive integer, so it's a natural number. yes, it's a whole number. yes, it's an integer. it's a rational number as well because it can be written as a ratio (5/1). it's also a real number, because real numbers include rational numbers.

the only set that DOESN'T contain 5 is irrational numbers. 5 can be expressed as a ratio, so it can't be irrational.

Idk i am in 5th grade lol
