To which of the following sets does the number 0 belong?

a) integers
b) rational
c) whole
d) irrational
e)natural

The number 0 belongs to these sets: A. integers, B. rational, and C. whole.

It is rational because it is the ratio of two integers (namely zero and one). 

It is an integer because it fits the definition of integer. Integers are numbers in the set {...,-3, -2, -1, 0, 1, 2, 3,...} 

It is whole because it fits the definition of whole. Whole numbers are the set {0, 1, 2, 3, ...} 

It is not irrational because it's rational. 

It is not natural because the lowest natural number is 1.

The number 0 belongs to integer, whole and rational number (a, b, c)

Further explanation

Numbers are quantities used in measurements

Numbers in mathematics can be divided into several terms

1. integer

numbers consist of positive, negative and 0 numbers

2. natural numbers

numbers consisting of positive numbers, starting with number 1

3. whole number

a number consists of positive numbers and zeros

4. prime number

numbers that can only be divided by numbers themselves and the number 1

5. Rational number

Numbers that can be expressed in a / b comparisons where a, b are integers and b does not equal 0.

And examples of other numbers such as real numbers, real numbers, etc.

Integers themselves consist of

1. positive integers

the number to the right of the number 0 is 1,2,3 ...

2. negative integers

the numbers to the left of the zeros are -1, -2, -3 ...

3. number 0

So The number 0 belongs to

1.integers

number 0 is included in integers

2. rational

number 0 can be expressed in the ratio a / b with the values a = 0 and b = / 0

, and

3. whole number

number 0 is included in the whole number

The correct answer is -20y

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.
