QuestionWhich of the following describe -4 ? Select all that apply. whole number irrational number real number integer

Studdy Solution

STEP 1

What is this asking? We need to figure out which number categories -4 belongs to. Watch out! Don't mix up integers and whole numbers!

STEP 2

1. Check if -4 is a whole number.
2. Check if -4 is irrational.
3. Check if -4 is real.
4. Check if -4 is an integer.

STEP 3

Whole numbers are like counting numbers starting from zero: 0, 1, 2, 3, and so on.
Since $-4$ is negative, it's not a whole number.

STEP 4

Irrational numbers can't be written as a fraction of two integers.
Think of numbers like $\pi$ or $\sqrt{2}$ .
Since we can write $-4$ as $\frac{-4}{1}$ , it's not irrational!

STEP 5

Real numbers are pretty much any number you can think of that's not imaginary (like $\sqrt{-1}$ ).
Since $-4$ doesn't involve imaginary numbers, it is a real number!

STEP 6

Integers are like whole numbers, but they also include negative numbers.
So, $-4$ , $-3$ , $-2$ , $-1$ , $0$ , $1$ , $2$ , and so on, are all integers.
Since $-4$ fits right in there, it is an integer!

STEP 7

$-4$ is a real number and an integer.

STEP 2

1. Check if -4 is a whole number.2. Check if -4 is irrational.3. Check if -4 is real.4. Check if -4 is an integer.

STEP 3

Whole numbers are like counting numbers starting from zero: 0, 1, 2, 3, and so on.Since −4-4−4 is negative, it's *not* a whole number.

STEP 4

Irrational numbers can't be written as a fraction of two integers.Think of numbers like π\piπ or 2\sqrt{2}2​.Since we can write −4-4−4 as −41\frac{-4}{1}1−4​, it's *not* irrational!

STEP 5

Real numbers are pretty much any number you can think of that's not imaginary (like −1\sqrt{-1}−1​).Since −4-4−4 doesn't involve imaginary numbers, it *is* a real number!

STEP 6

Integers are like whole numbers, but they also include negative numbers.So, −4-4−4, −3-3−3, −2-2−2, −1-1−1, 000, 111, 222, and so on, are all integers.Since −4-4−4 fits right in there, it *is* an integer!

STEP 7

−4-4−4 is a real number and an integer.
